How to filter team from causing damage to func_button

Hello

I have a func_button that triggers an event when it receives damage.
But I only want the event to happen when one team causes the damage.

Is this possible, the two idea's I had are as follows, other than that I'm stumped.

The first was to try and block one team from causing damage, so i know that it was the other team that triggered it, which I could not figure out how to do.

The other alternative i considered, is there there some way of knowing which team's rocket caused the damage and then somehow use that.

Any ideas, thanks in advance for helping.

wow, I feel like a fool, I looked at that but because of the "associate control point" option i assumed it could only be used with CPs, guess i was wrong.

It works perfectly now, exactly what i wanted.

Cheers
