So I'm trying to figure out how to do this. Here's the scenario.  Case worker comes back to the office and "checks in" documents they've had in the field.  I would like to be able to have an email be sent to the case worker 3 months from when they check the document back in so that they know they have to review it.  I'm fine if they get an email for each document needing reviewed, but I'm having a tough time understanding how to use the Date Token Calculator and what to do with it to accomplish my task.

Thanks!
