Pass Multiple Values.

I’m using  SAP BusinessObjects XI 3.1. and is trying to pass parameters between two documents.

And found a document

“ Step-by-step Guide to Linking
WebI Documents using OpenDocument in SAP BusinessObjects Enterprise XI 3.1 “ by Vineeta Singh

Passing a Single Value works great, but I need to Pass Multiple Values.

   For example I selected two groups when I refresh data in from A. How do I transfer this to form B?

   I tried the hyperlink;

http://stjh1482:8080/OpenDocument/opendoc/openDocument.jsp?iDocID=5157&sType=wid&sRefresh=Y&sWindow=new&lsMgrp=(UserResponse("
Assignment-Group:")) but  I get “no data”

   What amI doing wrong?
