Happy to help.
Your command looks correct in your button rule. Your mapping looks fine.
But it seems that your form has custom code outside of qRules - and, in fact, qRules has been disabled by the addition of code. Is the custom code intentional? Or did you accidentally add it?
If you want to have custom code and use qRules, that is possible - let me know and I'll get you a link to a document explaining how to set this up.
Otherwise, from Tool / Form Options / Programming (for IP 2007) or File / Info / Form Options / Programming (for IP 2010), select Remove Code then reinject your template with qRules again.
Drag the Error node from the Qdabra Rules data source onto your form so that if you get an error, you can post it here.
A quick way to make sure qRules is injected and working correctly is to drag the Command and Result nodes from the Qdabra Rules data source onto your form and preview. Type GenerateGuid into the Command field and tab out - you should see the Command field set back to blank, and a GUID in the Result node. If you don't, something is still not set up right.
