Thank you somuch for all your help.
I identified the problem but no clue how to fix it now. This is the problem. My query which the report is based on is a crosstab query. The output of the base query is like this
Id REC_NUM Type Count
100 00 RN 10
100 00 PT 5
100 00 HHA 4
100 00 Other 3
100 01 RN 5
100 01 PT 6
The output of Crosstab is like this
ID REC_NUM RN PT HHA Other
100 00 10 5 4 3
100 01 5 6 0 0
Now the problem comes, when I filter out using the date parameter in the query sometimes RN, HHA, PT, or Other may not exist in the output, but my report expects those
fields as output. I don't know how to make the report run even if some fields are not returned.
Any ideas?
