"Cannot return codereturnsboolean to boolean" ?

Hi!

I never seem to correctly understand how to properly use functions (Or, in this case methods) as condition...

I'm sure I've asked this same question here several times, though I never seem to remeber it

Anyways, I'm getting an error in this line:
[ljass] if .u != null and (.xincrement != 0 or .yincrement != 0 or .zincrement != 0) and function thistype.Filters then[/ljass]

In this code:

library ScaleandFade uses T32

Thanks !!!
I always forget those brackets XD
