OpenDoc for Range of values

Hi Experts,

I have a requirement of calling a child webi document by passing a Range of values for Category from my webi using Opendoc.

So in the webi report created a prompt for Category with Inlist as operator with optional promt.

I created the below URL to access the child webi from webi but it not taking the specified range. Instead of that it always asking for prompt values.

To access the webi report -

http:../../opendoc/openDocument.jsp?sIDType=CUID&iDocID=ATmmMaij5dREu9oSzlCkPEs&sReportName=AC&sRefresh=Y&lsREnterCategory=[6000..6009]

please suggest whether anything is wrong in my URL syntax or in the webi prompt operator.

Thanks in advance

Prasanna.
