Im making a script manager for myself (i know that there already exists one).

I keep getting the error "autorun.lua:68: attempt to index global 'cb1' (a nil value)" even though ive already defined it.

The line is cb1:text(" "), so the problem might be that im using ":text" but on the wiki it states that checkboxes have that function.

Full code

On line 25 you have rBtn:action(refresh(1)), this is where it attemptd to run the refresh function before cb1 is defined. You probably meant rBtn:action(refresh).

I'm not sure if you can put arguments into this function ... might have to make it call a separate function which calls refresh(1).

Thanks this worked :) i just made it so it runs another function which sets top_stack to 1 and then run refresh

...There's a way to make what you want (pass the single argument onto the function but not call the function), it's sort of like Haskell's currying so I'll name it

curry

:

function curry(f, a)
  return function() 
     return f(a) 
  end
end

However this function is only useful in your case where it only takes 1 value.
So how you'd use it is this:

rBtn:action(curry(refresh, 1))

Checkbox is a nil value
