Automate email from date on Form

I would like to have a preset reminder message emailed to a person listed in a form 2 days before a set date from a field in a form. Also if this person marks the task as complete before that date I would like the auto email feature to be disabled.

Thanks.

You could write a scheduled agent that runs daily that checks the date against the current date and providing the status is not complete, sends a reminder email.

Hope this helps,
