Reports :: DCount - Give Count Of Each Attending Equaling Yes Only

I have this query:

ID Attending Trauma RN Date
1 A No Yes 1/1/12
1 A Yes No 2/1/12
1 B No Yes 1/1/12
1 A Yes No 3/1/12
1 B No Yes 6/1/12

I merged this query into a report to give the count of each attending equaling yes only. I am using this:

=DCount("*","qryMainJan-Jun13","[PeripartumHysterectomy] ='Yes' And [Text30] = ID")

The goal is to show each attending on a separate page with count on text box

The issue I am having is I can't show the correct total in one page for each attending. for example I am showing attending A twice for trauma with total 1 for each page. I need to show attending A with total 2.
