in the Report R2 had the Same Parameters Start Date and End Date

When User Runs the Report R2 with the parameters Start Date and End Date in the Report R2 I had Kept a Hyper Link Where user can  Redirect to R1 (ID 5667)

http://servername:8080/BOE/CrystalReports/viewrpt.cwr?id=5667&apsuser=abcd&apspassword=efgh&apsauthtype=secEnterprise

This is the Hyper link That i am using  Redirect  how can i Pass the Start Date and End Date Dynamically to R2 Report

what will be the Code to Pass the parameters from R1 --> R2 report

Thanks
