Hey Folks

Sorry to ask about such a simple thing, but I can't seem to find it anywhere.  I have need of an OR statement, but I can't seem to find how to do it.

Basically I need to make an IF where Term A is met, and either Term B or Term C & D is/are also met.

can anyone tell me how to do this without using nested IFs, because I'ts to perform a lot of code, and I don't want to have it appearing twice.  I've tried using "OR" but that didn't work.  Is there a term I'm missing, or is it completely impossible?

Cheers all
