Submitting Concurrent Request using FND_REQUEST.SUBMIT_REQUEST not working

I am trying to submit a concurrent request within a form using FND_REQUEST.SUBMIT_REQUEST and it's not submitting the concurrent request.  It's sets the request id and gives me that number back but never submits the report to the concurrent manager.  Can anyone help with this issue.  Here's the code I'm using:

declare

x_set_print boolean;
x_request_id number := 0;

begin

x_set_print := fnd_request.set_print_options(:printer_blk.printer_name,null,0,TRUE,'N');

x_request_id := fnd_request.submit_request('CVI','CVIWOSHEET','CVI - Work Orders',NULL, FALSE,
                            :header_blk.job_number,
                            '', '', '', '', '', '', '', '', '',
