So I have two scripts, one to harvest the item and one for the inventory system. The inventory system has to press 'F' to collect and then 'Click' to harvest. I just want to merge the two to work together here's the first one:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local UserInputService = game:GetService("UserInputService")

local Player = game:GetService("Players").LocalPlayer
repeat wait() until Player.Character wait()
local Mouse = Player:GetMouse()
local Camera = game.Workspace.CurrentCamera
local promptHint = Player.PlayerGui:WaitForChild("ScreenGui").prompt
local promptHintTwo = Player.PlayerGui.ScreenGui.prompt2
local currentInventory = Player.PlayerGui.ScreenGui.currentInventory
local currentInventoryTitle = Player.PlayerGui.ScreenGui.currentInventoryTitle
local currentInventoryCurrentCapacity = Player.PlayerGui.ScreenGui.currentInventoryCurrentCapacity
local currentInventoryMaxCapacity = Player.PlayerGui.ScreenGui.currentInventoryMaxCapacity

--"distance" player needs to be inside to see prompt to pick up item
local magnitudeNearItem = 10
--local max capacity player can carry
local carryWeight = 10
--amount of capacity currently player has
local currentWeight = 0

--Creating a player's inventory
local playerInventory = Instance.new("Folder")
playerInventory.Parent = ReplicatedStorage
playerInventory.Name = Player.Name.."'s Inventory"

--Detecting if a player's mouse is hovering over a pickable object. If they are, then show promptHint.
UserInputService.InputChanged:Connect(function(inputObject)
	if inputObject.UserInputType == Enum.UserInputType.MouseMovement and Mouse.Target ~= nil and Mouse.Target:FindFirstChild("isPickable").Value == 1 and((Player.Character.Torso.Position - Mouse.Target.Position).magnitude)<magnitudeNearItem then
		promptHint.Visible = true
		promptHint.Text = "PRESS 'F' TO PICK UP"
	else 
		promptHint.Visible = false
	end
end)

UserInputService.InputBegan:Connect(function(input,GPE)
	--If key is "F", then put item into player's inventory.
	if input.KeyCode == Enum.KeyCode.F and Mouse.Target ~= nil and Mouse.Target:FindFirstChild("isPickable") and((Player.Character.Torso.Position - Mouse.Target.Position).magnitude)<magnitudeNearItem and not GPE then
		--Gets data from modulescript from item
		local itemData = require(Mouse.Target.itemSettings)
		--if its possible to carry then add to inventory, else prompt saying can't carry anymore
		if (currentWeight+itemData.weight) <= carryWeight then
			currentWeight = currentWeight + itemData.weight
			Mouse.Target.Parent = playerInventory
		else
			spawn(function()
				promptHintTwo.Visible = true
				promptHintTwo.Text = "CANNOT CARRY ANY MORE ITEMS"
				wait(1)
				promptHintTwo.Visible = false
			end)
		end
	--If key is "G", then list all items in inventory in output.
	else if input.KeyCode == Enum.KeyCode.G and not GPE then
		local inventoryChildren = playerInventory:GetChildren()
		local inventoryString = ""
		for i=1, #inventoryChildren do
			--Gets data from modulescript from item
			local itemData = require(inventoryChildren[i].itemSettings)
			inventoryString = inventoryString..itemData.name..", "
		end
		currentInventoryTitle.Visible = true
		currentInventory.Visible = true
		currentInventory.Text = inventoryString
		currentInventoryCurrentCapacity.Visible = true
		currentInventoryCurrentCapacity.Text = "CURRENT CAPACITY: "..currentWeight
		currentInventoryMaxCapacity.Visible = true
		currentInventoryMaxCapacity.Text = "MAXIMUM CAPACITY: "..carryWeight
	--If key is "E", then empty out all inventory back into game. Objects are positioned in direction player is facing, and larger objects are placed farther away.
	else if input.KeyCode == Enum.KeyCode.E and not GPE then
		local inventoryChildren = playerInventory:GetChildren()
		for i=1, #inventoryChildren do
			inventoryChildren[i].Parent = workspace
			inventoryChildren[i].CFrame = Player.Character.Torso.CFrame + (Player.Character.Torso.CFrame.lookVector * inventoryChildren[i].Size)
			wait()
		end
		--remove item from inventory currentWeight = currentWeight - itemLeaving.weight. since this just removes all items: currenWeight is set to 0
		currentWeight = 0
	end
	end
	end
end)

UserInputService.InputEnded:Connect(function(input,GPE)
	--If player lets go of "G", then take off GUIs.
	if input.KeyCode == Enum.KeyCode.G and not GPE then
		currentInventoryTitle.Visible = false
		currentInventory.Visible = false
		currentInventoryCurrentCapacity.Visible = false
		currentInventoryMaxCapacity.Visible = false
	end
end)

--If player dies, remove all items in inventory
Player.Character.Humanoid.Died:Connect(function()
	playerInventory:ClearAllChildren()
end)

and the second:

local model = script.Parent.Parent
local brick = script.Parent
local gui = brick.BillboardGui
local click = brick.ClickDetector
local text = gui.TextBox
local scroll = gui.Scroll
local click = script.Parent.ClickDetector
local branches = script.Parent.Parent.branches:GetChildren()
local isPickable = brick.isPickable
scroll.Size = (UDim2.new(0,5,0,5))
val = 0

local function onMouseClick(player)
	text.Text = "Harvesting..."
	repeat
		val = val + 1
		scroll.Size = (UDim2.new(val, 5, 0, 5))
		wait(3)
		if val>=1 then
			break
		end
	until val==1
	text.Text = "Harvested!"
	isPickable = 1
	brick.Transparency = 1
	brick.CanCollide = false
	scroll.Size = (UDim2.new(0,5,0,5))
	
	wait(1) -- Split
	for i = 0.1, 1, 0.1 do
    for i,v in pairs(branches) do
        v.Transparency = i
    end
    wait(0.1)

	model:Destroy()
	print("killed")
	end
end

click.MouseClick:connect(onMouseClick)
