Accessing the parameters passed from other URL is SSRS 2005

Hi,

    I have 2 reports Say report1 and report2 created in SSRS 2005, Report1 is summary report and report2 is detailed report of report1.

    We have one column in report1 which is used as link to report2,

    when clicking on the link i need to pass values needed for report2 and by default report2 had to accept this parameter and load the data. I am already passing URL like below:

"localhost/Reports1/Pages/Report.aspx?ItemPath=%2fBFT+Dev%2fInterestDetl&rs:Command=Render&rc:Parameters=false&Our_Entity=Lum%20Eny%20Crit%20Canada%20LimitedCounterparty=Total%20Interest%20Received"

  but when i run the report with this URL i am getting below error

       "

The 'Our_E

ntity' para

meter is missing a value "

  My question here is:

• How to pass parameter values into parameter of the another report.?

  Keeping the parameter in hidden state, how to assign parameter values in run time.?

•  have Our_Entity and Counterparty parameters hidden in Report2. 
• Can anyone please help me in resolving this issue. 
• what might be the issue with the URL passed.

• Thanks everyone for your kind support in resolving this issue.

• Thanks,

  Santhosh Shivaram
