Multiple values in a single parameter and show multiple page report in CR

Dear all,

I need a report which will have a feature. A single parameter will be able to take multiple values, and each value will show a different report with paging. Actually, we have to generate invoices. the parameter will be the customer ID. 3 selection of customerID from a popUP, will cause a report of 3 page of 3 different customers.

How can i obtain this.

Let me be clear, i have tried to use 'Section Expert' and 'New page after'. It didn't work. I tried to give option to the parameter field of 'Allow multiple values' also don't work. The parameter is given from a stored procedure.

Please help.

TIA.
