How can I merge these two scripts into one function for a click detector block?

First of all, don't use other peoples scripts(unless its for learning purposes of course!), no one ever made a good game without making their own scripts and learning, plenty of resources out there, start at (wiki.roblox.com).

[[QUICK EXPLANATION]] Basically I combined the two functions and had one brick call that big function, let me know if I need to elaborate more of this doesn't work.

--ORIGINAL FUNCTION 1

local script1 = workspace.script1 -- Put location of your script you want to enable/disable
function onButtonClicked()
script1.Disabled = false
end
script.Parent.MouseButton1Down:connect(onButtonClicked)

--ORIGINAL FUNCTION 2

local serverstorage = game:GetService("ServerStorage") -- serverstorage is the service to store whatever you want in, Lighting was used before ServerStorage was made

local model = serverstorage:WaitForChild("cheese") -- replace "cheese" with the name of the model under serverstorage
local brick = script.Parent -- variable for the parent of the script, which is what the clickdetector is going to be under
local detector = Instance.new("ClickDetector", brick) -- creating a clickdetector, which is used to be able to click a specific part, and parenting it to the script's parent.

local isinwork = false -- creating debounce for later usage

--[[You have to already have the model positioned as you want it to be shown as, in serverstorage, when it's parented to workspace it will be shown in the position you had it at when u stored the model in serverstorage]]--

function moveModel() -- function that will be called when someone clicks the part
    if not isinwork then  -- checking if the debounce is false, if it is then it will parent it to workspace
        model.Parent = game.Workspace
        isinwork = true -- here it is setting the debounce to true so when it's clicked again it is parented to serverstorage
    else -- if the debounce is true then it will parent it to serverstorage
        model.Parent = serverstorage
        isinwork = false -- here it is setting the debounce to false so when it's clicked again it is parented to workspace
    end
end

detector.MouseClick:connect(moveModel) -- calling the function when the brick has been clicked

--NEW SCRIPT

--First let's declare our variable from both scripts!

-------Variables
brick = game.Workspace.brick -- put the path to brick HERE
local serverstorage = game:GetService("ServerStorage")
local model = serverstorage:WaitForChild("cheese")
local detector = Instance.new("ClickDetector", brick) --THIS IS THE ONE CLICKABLE BRICK
local script1 = game.Workspace.script1

local isinwork = false --Debounce Variable

--Next we need our event, which you specified as the click on the clickdetector, we will just attach a big function to this that has both functions combined

detector.MouseClick:connect(function()

	if not isinwork then  -- checking if the debounce is false, if it is then it will parent it to workspace
        	model.Parent = game.Workspace
       		isinwork = true -- here it is setting the debounce to true so when it's clicked again it is 		parented to serverstorage
   	else -- if the debounce is true then it will parent it to serverstorage
        	model.Parent = serverstorage
        	isinwork = false -- here it is setting the debounce to false so when it's clicked again it is parented to workspace
	end -- UPDATE: FORGOT TO CLOSE THE IF STATEMENT SORRY :P!

	--END OF FIRST FUNCTION | BEGINNING OF NEXT FUNCTION

	script1.Disabled = false

end) -- Close the parenthesis
