I am interested in calculating the expiration date of a link, based on the Modified tag (a date) and the Expire tag (number of days), and using this as another tag which I'll refer to as Expire_Date.
According to Lepo, this should be possible. He provided me an equation for doing this but, as I am not a programmer, I am stumped.
Based on the reply he's provided below, would someone be willing to work up some code that I could cut/paste into Emailizer to do this?
Thanks tremendously in advance!
