Does anyone know if there is a way of referencing dates based on the existing date tags? For example if today is the 19th May, I'd like to reference the last day of next month (I'm thinking about how long something is valid for). So how do I reference 30th June? Or if today is 2nd December 2011 my expiry date might be 31st January 2012.
Hi a1_mark, welcome to the forums! We can't perform date logic in the app as yet, I'm sorry to say. However, if you're planning on calculating dates when someone signs up to your list (ie. subscribe date is today, expiry is one month from now), you could try creating two custom fields, adding a date calculation script to your subscribe form and passing the date values to your custom fields when someone subscribes.
Anything more complex than that will require using our API. Hope that helps!
