Here's how to use pcall: (and of course its setup to fail....)

Change NILVALUE to "HI" for fail to be false and get the success message to print .

local NILVALUE = nil
local success, fail = pcall(function()
		print("this is a test")
		print("Concatenate a value: "..NILVALUE)
end)

if fail then
	print("Failure: "..fail) -- your failure reason will be here
	return
end

print("we succeeded!!!")
