We've built a request form.  These is a status section (that workflows are triggered by) with the dropdown choices:  New Request, Request Submitted, Returned Request, Approved, Request Rejected, Request Evaluated, etc.  Within the form we have the standard save and submit button.  The Request Rejected has another button:  Resubmit.  (when the rejected request is approved, the resubmit button should set it to the default stage of Request Submitted.  In the control setting I set up the button.  It returns the value, Request Submitted in the Status section (of the list), but it does not change the status in the form (dropdown).  What it is basically doing (on the form) is keeping the Request Rejected, but adding the Requested Submitted to the List.  I just need it to replace the Request Rejected status to Request Submitted
