Eloqua "between" operator
I'm creating a segment using filter "Compare Contact Fields":
Contacts who have a "Zip or Postal Code" field having a value that is between "0000" and "0100".
We have four-digit zip codes in this country. However, Eloqua returns zip codes such as 123498 and even zip codes with letters in them, such as NZ-13265.
Am I doing something wrong?
Any help appreciated!
