I have been working for a little while now, but cant seem to get away from this error:

Start

7: $smugset = 1
8: $sickset = 1

32: if ($happyset = 1)($happy = true)
> Error on line 32: Missing binary operator: 
True [?] False
Done (00:00:00.1020057)

Any ideas where it comes from? How could i fix it? If the EZ-Script is nessesary, I'll post it, but its from a project that i don't want to release just yet. This is the main dispatcher script causing the trouble.
