Available holds

Hi, 

I have a pivot chart in analytics that tells me the number of holds, opens, comps, capacity etc for each performance. The issue is my 'holds' are calculating any hold; whether it's been ticketed or not. So those holds that have been ticketed (whether paid or comp'd) are being calculated twice: in holds and in comp or paid, which is then skewing opens. I'd like for holds to only calculate 'available' holds but I can't figure out how to do that in the formula. Any suggestions please?

Thank you!
