How can i prevent players placing crops on the same farm plot location?

(insert something here that gets me 10000000000000000000M rep)

Hi, its a me! BashGuy10. After playing a lot of farming games, i had inspiration to make my own, one of the problems i've encountered is: Stoping the player from placing on the same farm plot that already has a crop.

Does anybody know how to fix this?

I've already tryed using mouse.Target:GetChildren() to see if there is not any crops already placed, but it stops the ability to even place!

Local script

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local currentobject = plr:FindFirstChild("CurrentObject") 

local UIS = game:GetService("UserInputService")

local activekeycode = Enum.KeyCode.B
local active = true

local frame = script.Parent.Place
local rp = game:GetService("ReplicatedStorage")
local crops = rp:WaitForChild("CropModels")
local event = rp:WaitForChild("PlaceCrop")

for i, v in pairs(frame:GetChildren()) do
    local model = crops:FindFirstChild(v.Name)

    v.MouseButton1Click:Connect(function()
        if model then
            if not active and currentobject.Value ~= model then

                rp:WaitForChild("ChangeCrop"):FireServer(model)
            end
        end
    end)
end

UIS.InputBegan:Connect(function(input)
    if input.KeyCode == activekeycode then
        if active then
            print(active)
            active = false
        elseif not active then
            print(active)
            active = true
        end
    end
end)

local plantdb = false

mouse.Button1Down:Connect(function()
    print("yeet")
    if active and not plantdb then
        print("yeet2")
        if mouse.Target.Name == "Plot" and not mouse.Target:GetChildren() then
            print("yeet3")

            event:FireServer(mouse.Target)
        end
    end
end)

Server script

game.ReplicatedStorage.PlaceCrop.OnServerEvent:Connect(function(plr, target)
    print("yeet4")
    local clone = plr:FindFirstChild("CurrrentObject").Value:Clone()
    clone.Parent = target
    clone:SetPrimaryPartCFrame(target.CFrame)
    print("yeet65")
end)
