I am getting an error like "the value expression for the query parmeter '@TITLE' refers to non existing parameter 'TITLE' . letters in the names of the parameters must use the correct case" Please help me...

Hi Jyo1105, As Nehemiah and Tom posted, it might be caused that the parameter are case sensitive. The error message shows that “non existing parameter start_date”, I suggest you to check the correct case of the “START_DATE” parameter was used. By the way, please ensure that the “START_DATE” parameter is added to your report. Hope this helps. Regards, Bin Long
