Help with a script that is supposed to make a text effect on a text label?

My script


~~~~~~~~~~~~~~~~~
local textLabel = script.Parent:WaitForChild("TextLabel")
wait(4)

local function typewrite(object,text)
	for i = 1,#text, 1 do
		object.Tect = string.sub(text,1,i)
		wait(0.05)
	end
end
~~~~~~~~~~~~~~~~~


typewrite(textLabel, "Welcome to the match!")**

It is supposed to make a typewrite effect, it will write on the text label with each character on a wait to make it look like it is writing.. But it is not working. Please help.
