By the description this would seem to be the CF I need. However I am not sure of how to craft it into my database. Can ORDERED and RENEW.PERIOD take fields? Is ORDERED a field listing the renewal dates by return-delimited?

Hi TKnTexas, As with all custom functions, you'll need to import this into your filemaker pro database using the Manage Custom Functions area of Filemaker Pro. ORDERED and RENEW.PERIOD are required fields - ORDERED is a date field; RENEW.PERIOD is a positive integer. The result of the calculation is the next renewal date, based upon the current date of the host system. It won't provide a tab-delimited list of dates, unless you write a script to do so.

Thanks James. I got the function into the right place of Filemaker. I am just not understanding it to integrate the function into use.
