attempt to call nil

Sorry if this is a stupid question, but I am new to programming and even newer to Lua

Here's my code

print("How High?")
h = tonumber(read())
	 turtle.goUp(h)
	 turtle.select(1)
	 if turtle.getItemCount(1) < 1 then
		  turtle.select(2)
	 end
	 turlte.place()
print("Your Platform is complete")

it gives me an attempt to call nil error on the line with

turtle.goUp(h)

any help would be appreciated, I just can't figure out what I am doing wrong, I come from a Java background, so some of this syntax is somewhat frustrating. This is probably really simple, I just want to start learning some Lua, because this mod is really interesting

first, it's turtle.up().

Second, turtle.up() dont accept any arguments, so running it many times will make you have to use a for loop.

Oh wow, I'm feel stupid now, thank you so much, I probably should have noticed that… I guess I shouldn't assume things have arguements

Thanks for the quick response!
