Crystal Report ... Can't figure out why does this happens

Hi there,

I have created a Stored Procedure (SP) in MS Sql 2000 which accepts 4 parameters. I have created a Report using Crystal Report (CR) 7.0.0.0. Now the report was created using this SP. From my Visual Basic 6 application, I pass this 4 parameters to CR and most importantly it displays the Report as desired.

The problem starts now, when I deployed the same at clients place and tried to execute the same, it prompted me for the 4 parameters values rather than taking it from my vb6 application. Any idea why does it behave like that.

waiting for your assitances
Thanx in advance.
