Welcome to AutoIt and the forum!

"[, hwnd]" denotes an optional parameter in the syntax description of the language.

You need to replace "[, hwnd]" by a window handle or remove it.

Actually, pajamac, your problem is on line 18,  not 19. 

; this

$pos = MouseGetPos

; needs to be written like this
$pos = MouseGetPos() ; <<<<< note the parentheses

There are several syntax errors in the posted script, so maybe you want to ensure you use au3check to help you get these identified.
