Additionally, I have checked all existing Rules and none use this variable.

Hi!   In Admin > Classification Rule Builder > [create/edit rule] > Select Report Suites and Variables, why are some variables grayed out after selecting a report suite? What settings do I change to enable these variables?   I have enabled the Conversion Variable and I have associated the Conversion...

got it. thank you!

thank you both! I have everything working now. I am curious though, what happens if I have a single classification rule set with multiple rules using the same Classification but the To field is set to different RegEx groups ($1, $2, $3, etc)?

Thanks! I got the dimension to show up! unfortunately, its only results are "Unspecified". Does this indicate a bad setting? Or perhaps I need to wait for the rule to run?

Maybe I skipped a step? All I did was create a rule in Admin > Rule Classification Builder. The rule is active, but do I need to add the rule somewhere else?

Thanks you both for the help. I'm not sure what the next step is after creating a classification rule, I had assumed that it would be available as a dimension, but that does not seem to be the case.
