I've created a custom field label with the inputs below:
Field Type: Date Picker
Save Format: yymmdd
Display Format: mm/dd/yy
In Gravity Forms:
Field Type: Date
Custom Field Name: Existing
Date Input Type: Date Picker
Date Format: mm/dd/yy
But when the form is submitted, the date chosen is not passed through to the custom field label in the draft post. Everything else seems to work fine.
There was a post about it a while back but it doesn't look like it was ever resolved: http://wordpress.org/support/topic/date-format-value-did-not-passed-to-the-custom-field-created?replies=1.
Any suggestions would be greatly appreciated!
