Hi there.

I am writing a display API for a few programs I am working on.
Problem is I can't even get the first function to work.

Here's the code I have so far:

local display = term
local tX, tY = display.getSize()

function centerAlign(text,y)
  display.setCursorPos(tX/2-#text/2,y)
  display.print(text)
end

Every time I run the function, I get the error window:248: bad argument: double expected, got nil

Can anyone tell me what's up?

What are you passing into centerAlign? My guess is that you aren't passing in a y-value.

Edit: Also, term.print is not a thing

Also print is not a term function, use write instead.
