Using Drilldowngrouplevel on specific fields

[checkai]

I am formatting fields differently depending on which level of drill down i am at. Example: when drilling down on the first set of data I put a Line above the subtotals.

Here's the problem...it works sometimes...not others....within the same report i have drill down levels that all the formatting works correctly and then the next level down (formulas should be correct, just add 1 to the drilldown level) nothing gets formatted...

any suggestions?

Thanks!!!
