passing data from Select Statement to Insert using FormView

I'm using FromView - please see the attached. I'm retrieving Acct_ID among other data from the DB. In the Insert statement I would like to use the same Acct_ID i got earlier but my text box doesn't get populated with it. How can I get it accomplished in FormView?
Thanks for your help.
