We are trying to set up a process where if a person submits a form, and a non-required field is left empty, we infer that means the person no longer has that item.
Example: Bill told us 4 years ago he grows Rice. This year he renews his subscription to our magazine and leaves Rice blank (we cannot pre-fill per print audit rules). We want to have Marketo wipe out his previous answer and assume he no longer grows rice.
Can that be accomplished?
I thought perhaps have some sort of trigger campaign but that will overload our system and create a log jam in our Campaign Queue.
Ideas?
That's the exact situation I covered here: http://blog.teknkl.com/clearing-lead-fields-when-no-value-submitted/
