My form contains a field which the end-user selects a date from a popup calendar. With the date selected I would like to add 90 days to it and post it in another field. Does anyone have an idea how to complete this task? Any help would be appreciated.
Thanks for your help, but I still don't seem to understand how to do this. I have placed this code on my field that the end-user selects the date. And have named this field givenDate. My other field that I want the date + 90 I have named "Dateafter90". If you could provide a little more help I would appreciate it. I am a novice and this is a little over my head.
