At the moment I have used +days to add the frequency as days,.
but I need it in weeks. I cant see a way of displaying or calculating the number of days converted from weeks, I cant see a simple way to multiply weeks x 7 to give days to add to the last visit date to give the next date.
Hey! You can calculate it by just multiplying the weeks by 7. For example: Last Visit Date + (Frequency in Weeks * 7) days. That will give you the next due date easily.
