Parse Error Problem

[SuperSlothStudios]

Hello my partner and I were trying to do the tutorial for AGS but we ran into a parse error. We followed the instructions exactly but we keep getting the same error. If anyone can help we would be extremely grateful.

Code: ags

function Okey_Interact()
{
  Okey.Visible - false;
  player.AddInventory(iKey);
  GiveScore(5);
}

The error is:
room1.asc(42): Error (line 42): PE04: parse error at 'Okey'

This

Code: ags

Okey.Visible - false;

should be:

Code: ags

Okey.Visible = false;
