How to add the flag for repeated rows

Hi,

I would like to add flag if the meeting id is diplayed more than once in the webi report.

I can have multiple hotels for same meeting id's. So i need identify how many meetings are getting repeated.

I tried with count(meetingID)>1, but in the report is treating as a sinlge row so i am always getting 1.

I tried with If( Previous(meetingID)=(MeetingId)) then "Y" else " ".

This time i am getting "Y" for the second row, but first row is blank.

I want to display "Y" for both rows if the program ID is getting repeated.

Attached the sample image.

Seeking for someone hlep.

Thanks in Advance,

Suri
