📌 Issue: Kajabi Zap Error – Required Field "Email" Missing from Trello/Crmble

What I’m trying to do:
I'm using Trello with the Crmble Power-Up and trying to send data from a Trello card to Kajabi via Zapier. The Zap is supposed to create a form submission in Kajabi when a new Trello card is created.

The problem:
Zapier throws this error:

❌ Failed to create a submission in Kajabi
Required field "Email" (email) is missing.

However, the email field is filled out in Trello — specifically in the Crmble layout using a multivalue field. Zapier doesn't seem to detect or pull the email from that field when testing the Zap.

What I’ve checked so far:

• The email field exists and is filled out on the Trello card.

• Crmble is using a multivalue field for email.

• In Zapier, the email mapping shows as blank — it doesn’t pull any email value.

• I suspect Zapier can’t “see” into Crmble’s multivalue format.

My question:
👉 How can I format or map the email field from Trello/Crmble so Zapier recognizes it as a valid email for the Kajabi form submission step?
Do I need to:

• Use a specific custom field in Trello for email instead of Crmble’s default?

• Flatten or convert the multivalue?

• Adjust the way Crmble saves email addresses?

Any help on how to make Zapier see and send that email field would be amazing.
