Triggering a campaign automation from a Form

Triggering a campaign automation from a Form

I used Forms to create a lead form that is accessed by a button on my website. The field information flows into the CRM. However, I am trying to figure out how to use Campaign automations to start a workflow (series of campaign emails) that is triggered when the form is filled out. I get a message that the form is already integrated with CRM so it cannot be integrated with Campaigns.
