how do i subtotal on groups based on a condition - crystal-reports

Question

My report is grouped on clinic, staffname with subtotals by clinic. I need to count patients by staff where they had more than 1 admit date. I can get the correct grand total, but on the detail and subtotals, it is a progressive number.
Here's what I want
clinic1
staffname1 10
staffname2 95
subtotal 105
clinic2
staffname3 6
subtotal 6
grand total 111
Here is what I get:
clinic1
staffname1 10
staffname2 105
subtotal 105
clinic2
staffname3 111
subtotal 111
grand total 111

Answer 1

A lot of this may depend on the structure of your data, e.g., what is in your "detail" level. I am also assuming that you want to count of how many patients had more than one admit date, not the total number of admits for patients with multiple admits. Given that, and assuming a patient will only appear once per admit date, then this should work:
Group by patient also, so it's clinic -> staff -> patient, but suppress that group.
Create a formula to count if the number of records in each patient group is more than 1, something like this: if count({patient},{patient}) > 1 then 1 else 0
Take the formula you just created, and use it to make a summary field wherever you want a total, e.g., in the staff head it will give you a count or that staff member, in clinic it will do so for clinic, etc.
Something else to consider: I'm guessing this could be intended to gauge staff on their quality by seeing how many patients had to seek additional treatment. Even if that's not the full intent, whatever this is being used for could be skewed by staff encountering more/fewer patients. For example, staff that have 10 readmits out of 100 visits would look worse than someone who only had 5 readmits, but had also only seen 20 patients.
So: Along with the metric on which you are requesting information, I would also add a ratio metric. In the staff header, this would be straightforward: count({patients}) / distinctcount({patients}) which will give you the ratio of distinct to repeat visits. Keep in mind also that this could skew high for a staff member that had, for example, 50 patients, but one of them came back a dozen times.

Answer 2

To get the count of the fields that has Greater than 1.
Assuming the count field is a database field and value coming directly from database
Create a formula #Count and write below code. Place the forumla in details.
:
if(databaswefield.count > 1)
then 1
else 0
Now take the summary of the #count formula in required group footers.
Let me know if you are looking for something different.

If I got your comment correctly.
Though you take distinct count you can use that in your calculations by storing the value in a shared variable. Something like below and you can retrive value from that variable
Shared Numbervar count;
count:=distinctcount(patientid)
