Hi there,

I got this working. Following is the method i used to make it work in case someone else is in same situation :

You need to add a function to validate the parameters.

Go to the Report Properties under the Report menu and place this code to the Code Tab.

Public Function CheckDate(SDate as Date, EDate as Date) as Integer

Dim msg as String

msg = ""

If (SDate > EDate) Then

msg="Start Date should not be later than End Date"

End If

If msg <> "" Then

MsgBox(msg, 16, "Parameter Validation Error")

Err.Raise(6,Report) 'Raise an overflow

End If

End Function

Then go to the Report Parameters and Add named it XXX with the datatype is string. Checked the Hidden and Allow blank value ckeckboxes. In Available Values choose Non-Queried and from Default Values choose Non-Queried in right side of textbox then press the FX button then paste this code.

=CODE.CheckDate( .Value)

Then press OK.

Thanks
