Currently the IF statement for OptionSet fields (integers) do not allow to check for null values. In case a user has no value selected for an OptionSet (for example a language OptionSet), the IF statement is not going to be evaluated. This might lead to lost information or it is impossible to have dynamicly build url strings, depending on the language of a contact, in case there's no language selected. From a marketing user's perspective, he always needs to know, whether or not a certain OptionSet he wants to check does have initial values checked. Please enhance the IF statement to evaluate NULL values in the ELSE part or create another HELPER to evaluate for NULL/UNDEFINED etc. Thank you and best regards, Philipp
