Pathfinder 1e Official Character Sheet Dynamic Reference Question

On the Official Pathfinder 1e character sheet, I am trying to write a simple macro to roll the caster level check so I might put it on the token tab. So on Pathfinder by Roll20 it says the dynamic reference for the roll is When I put the selected portion in the macro box, select the token and then hit the test macro I get the not found ability error. So my question is what is the real dynamic reference for this roll?

Whenever you are doubt about something like this, one way to be absolutely sure is to drag the roll button to the bottom of your sheet to add it to the quick macro bar.  That syntax (except that it will have your character name instead of selected) is what gets used by roll buttons dragged there, so you can drop the button on the bar, roll from the bar, then hit the up arrow with your cursor in chat to see the last command sent to chat.  It looks like at some point there was a dash somehow inserted in that, so it is now: %{selected|-RollCaster1Check}

Sweet, thanks for the tip and thanks for helping me out on this issue.
