Help I stuck on "This field cannot be summarized"

Question

I'm trying to build a report that measures the rate a clinic exceeds standard visit resolution.
For each Clinic I need a count of patients with 1 or more visits exceeding standard or @Yes_No = "Yes"
Group 1 = Clinic Name
Group 2 = PatID
Detail fields = PatID, VisitID, Visit Start Date, Visit End Date
A patient can have several visits
Here are my formulas
Code:
@HourstoResolve := DateDiff ("h",{@StartDateTime},{@Sh_OrderDateTime} )
Code:
@Yes_No :=
If
    (ToText({@Sh_OrderDateTime}) = "" or
    ISNULL({@HourstoResolve}) or
    ISNULL({@StartDateTime}) or
    {@HourstoResolve} > 2)
then
    "Yes"
else
    "No"
Code:
@ExceedStandard :=
If
    {@Yes_No} = "Yes"
Then
    1
Else
    0
I placed a RunningTotal Formula in the detail section but I still can't get the total by CLinic
Can anyone help?
Thanks
Steve

Hi Steve,
1) Change the @Yes_No code to:
If
    ({@Sh_OrderDateTime} = cdatetime(0,0,0,0,0,0) or
    {@HourstoResolve} = 0 or
    {@StartDateTime} = cdatetime(0,0,0,0,0,0) or
    {@HourstoResolve} > 2)
then
    1
2) Go to Insert Summary > Select this formula in the 'Field to Summarize' > Choose 'Sum' as the summary operation > Choose 'Group #1' as the Summary Location.
