Rule with Rule set as action - help with settings

Hi there, I need some help to get the proper set up working as needed.

I use Field formatter conditions, Rules and ImageCache Actions to set an image overlay when a node belongs to certain term ... That works just fine.

However, I need to set different image overlays for different terms and not sure how to accomplish this.

I've tried to set a rule set component were each rule would check for a term and if it does belong to it's term will set it's own image overlay ... however I don't get that to work.

Not sure if I'm choosing the right variables.

For this I set a new rule with the action is the rule set.

When I do this I'm asked to set some data selectors.

I'm not sure what is that I'm doing wrong, I think it could be choosing the wrong data selectors on this last step or setting the variable when creating the rule set.

Can someone give some directions to get this right?

Thanks
