Phizzy's advice is right - it seems that having to use "Compare two general values" instead of using an event provided by an object throws a lot of people at first. It did to me.
Yeh me too.
The "compare two values" event will probably prove to be very useful too - as there are a lot of objects which don't provide their own event like this. I don't remember TGF - but I'm pretty sure it had this event anyway.
