So here's my current code: 

function replaceString(s, f, r)
    s = tostring(s)
    local str, e = s:find(f)
	return s:sub(1, str-1)..r..s:sub(e+1, #s)
end

function stringToTable(s)
	local t = {}
	local currentString = ""
	for i = 1,#s do
		if string.sub(s,i,i) == "\n" then
			table.insert(t,currentString)
			currentString = ""
		else
			currentString = currentString..string.sub(s,i,i)
		end
	end
	return t
end

local linebreakTable = stringToTable(builtscript)
	local rebuild = ''
	for i,v in pairs(linebreakTable) do
		if string.find(v, 'PlayerGui') then
			v = replaceString(v, ':WaitForChild("PlayerGui")', '')
		end
		rebuild = rebuild .. string.format(tostring(v) .. '\n')
	end
	builtscript = rebuild

It should remove the :WaitForChild inside the lines that include PlayerGui right? Well ROBLOX doesn't think so.

Error: 140: attempt to perform arithmetic on local 'str' (a nil value)

I'm going to see if putting this script inside a Server-Script will fix anything.

The problem is in your replaceString function. Remember that error messages always mean what they say. You're attempting to preform arithmetic on str (line 4; str-1) which is a nil value. You should check if str exists before doing anything with it.
