The Find Contact feature inside of a workflow is very limiting. According to your tech support, basically, custom fields don't work right and there is no plan to fix it. I can search by SOME custom fields, and NOT by others. At first I thought it would search strings but not numbers, but even strings are sporadic. I specifically added a new string field and it didn't show up. This is a major bug, IMHO.

According to Ricky D. on ticket #2859042 "This would be because finding a contact based on a numeric custom field is a limitation of design within workflows"

Again, this simply doesn't work right. All fields should be searchable in the Find Contacts function in a work flow so that one can correctly pull a record based on it's status.

Thanks
