Hi, since nobody answered my question, I restructure my question again.

Ok before display a report, I want to come out a form which let users input their condition (eg. feb sales, march sales).

For the first time, the report will display result based on users input correctly. For the second time, the report still display result based on user's first time input even the second time input is different.

FYI, the datareport is bind to dataenvironment. I am suspecting whether datareport cache or dataenvironment cache problem.

Please show me the way and enlightenment. Thanks a lot!
