Do I use "Date of Issue" in the blank of "date of Marriage if no marriage date given?
Check your field help for the dates. When you click on Marriage Month, Date, Year, there will be a purple question mark that pops up. Click the question mark. There should be a priority list of dates to use then there is no marriage date given.
If not there, please post the batch code for a more accurate answer. The batch code is the series of numbers/letters in brackets at the end of the title. [XXXX-XXX]
