InfoPath Dev

I am trying to create an exception to a rule that I have set in my infopath document.  I am not sure if this is possible, but there should be some logical workaround that could be figured out I suppose.  Anyone know how I might go about this?

 Basically, I want a "ruleA" to apply when "X" = "Y" , but when "X" = "Y" + "Z"     (Z = some other option is selected in addition to Y) , then stop applying "ruleA" .......but when that "Z" factor is removed, I would like the ruleA to be applied again automatically as well.  I have this half working already, but I cannot get the rule to apply again after "Z" is removed (unselected) without infopath giving me an error "rule not applied; aborting..."

I hope this makes sense.  Thanks.

Rules allow you to have conditions. The set of actions will only apply if the condition is met. This might be part of what you need to solve your issue.

The other thing you might not have considered is that when Z changes, your rules on X will not be fired. You will need to have a rules on X *and* Z to get rules to fire in both situations.
