Thank you for your reply Mr. Halstead.
Sorry about the confusing scenario. I'll try to clarify it better:
Essentially, I am making a Workflow where, initially, the requestor will be limited to choosing 1 contact. After the form is submitted to SharePoint, I will wait say 1 day for the person selected in the Contact Selector to approve the form by pressing a Approve button in the form. If they do not approve it within 1 day, I want the requestor to go back into the submitted form (on SharePoint) and choose a different approver in the Contact Selector. I also want to keeping track of the AccountId of the contact previously selected so that he/she will have the ability to approve the form as well.
So this is all being done within the same form, not 2 separate forms.
