I'm trying to create my first s-control. It's used in a button to update the lead status to dead. My for the control is:

{!URLFOR($Action.Lead.Edit, Lead.Id,[retURL=URLFOR( $Action.Lead.View , Lead.Id ),lead.Status ="Dead", save=1] )}

type is URL.

It is not thowing an error, it just isn't updating the field.  Any reason this shouldn't work?
