This is how I'm trying to have my journey work...

1. guests are signing up for a class that starts on May 1st.  They are signing up with a form.

2. In the thank you email they are told to look for the next email to arrive  on May 1st, 2019.

When I attempt to add "date" element it gives me an error message that I can't have one trigger working with another trigger.

My current trigger is the sign up form.

Please help! :)

Thank you
