I am testing a schedule for the last date I then add on the scheduled delay to acheive the next due date.

Next due date is tested against weekends and moved if required to the next normal work day.

I thought it would be nice to pick up the last date logged in, and then test if any NextDueDates occur between the last log in date and the current log in date.

I have been able to pick up the last log in date and the current log in date. It is the testing that has me currently flumoxed?
