Using OpenDocument hyperlink in a Webi

I am trying to use opendocument in a webi. I have a cell set up with a hyperlink to the document. Linking to the report works, but I am having trouble passing the value of the cell as a parameter in the opendocument url to the prompts in the linked report. Here is the url I am currently using that does not work:

http://sapojd.cnsl.com:8080/BOE/OpenDocument/opendoc/openDocument.jsp?sIDType=CUID&iDocID=M1L5G0UAA0KJAFAAqAAAMz4GAgpXSIoAAAA&lsSEnter_DO_UID="+URLEncode(""+URLEncode(Char([Do Uid]))) +"&lsSInclude_Expired_Parties=Y

The parameter for which I am trying to pass the cell value is the lsSEnter_DOI_UID. Any ideas on what I am doing wrong?
