Stateless form + URL parameter + Web Page + Embed Report

Stateless form + URL parameter + Web Page + Embed Report

I have Stateless Form to enter userID and password, the workflow of the button onclick is OPENURL with URLparameter of userID and password to a Page.

In the page I'm using an embed Report.

Is it possible to add the URLparameter to the search string of the embedReport?

I tried different approaches most of the time it crashes and I have to delete the page and start over...

Thanks,
Martin
