Want to add a field to Campaign that displays # of Members who've made prior donations...

• The Prior Donations is a checkbox already on the Campaign Member object.

I tried to add a Rollup field to the Campaign Object which Counts Campaign Memeber records but when attempting to Filter the results based on Prior Donations = TRUE, the Prior Donations field is not not available in the Filter Criteria Fields. 

• Is there something I need to do to make the field available so I can use it as a Filter in the Rollup?
• If this can't be done, any suggestions on another solution?

#Campaigns  #Campaign Members  #Campaign Member Statuses  #Campaign Member  #Campaign  #Rollup Summary Field  #Roll-up Summary Fields  #Filter Criteria  #Sales Cloud

Thanks You, Glenn
