Signing Workflow: is it possible for the second and third signatory to sign the same form from their device and resubmit it?

Hi 

there is instances where I require a form to be co-signed via an e-signature. There may be up to 4 signatures required on one form. Once the first signatory signs the form and submits it, is it possible for the second and third signatory to sign the same form from their device and resubmit it?    

It is possible. You may take the example from this basic approval workflow guide: https://www.jotform.com/help/432-A-General-Approach-on-Building-an-Approval-Process-Workflow

Please give it a try, and let us know if you need more help.
