Hi Jamil,
Is main report parameter linked to sub report parameter ? I don't think you can link because, both are different data types and it will not allow you to link. Do you have two sets of parameters in Main report. ie. two start dates and two end dates ?
Is this parameters are created at report level or are coming from any command / stored procedure ?
Is it possible to send the report without data on sastrydsvs(at)gmail ?
Thanks,
Sastry
