Work Flow

Hi There,

I have a sheet that is filled in using a form, once the form is submitted, an approval request is submitted to the manager of the approve of which the approve provide the email address of the manager in the form. If the Manager reject the request, a notification is sent to the request to tell her /him that the request was rejected and informing him/her to what information is needed using the comment section. What I want to need how can I auto-send the approval request once the requester has done the changes that the manager has requested to be done for approval.

Kind Regards
