Hi,
I'm looking for a way to identify the number of days between card creation and the due date complete. I'd like to put this in an email report which I already have automated.
I've gotten as far as setting a custom field to set the date to "now" when a card is completed, but I can't seem to make any math of it and the creation date.
Am I missing something here? Do I need to convert the dates to numbers? and if so, could someone please help me with that part as well 
Thanks
