Numerical value "0" in data field not recognized by merge tag
I'm using merge tags to pull data into an email campaign. In this case, we are pulling a number that represents an interest rate. If the value in that data field for a given deal is "0" (zero), then the merge tag won't pull that number into the email copy. It will only pull the data in if I have a value greater than zero. Am I doing something wrong, or if the "field type" is set to "numerical" does it treat a value of "0" (zero) as just being an empty field?
