@deborahjtappan I appreciate you taking the time to respond.  I looked through our system and no employees that have been terminated have been rehired.  Though we do have one employee that was laid off and then rehired, but that happened well before this error started occurring.  In fact this employee was included on the payroll for the two dates that we are getting this error for. I am not sure if the system would have tried to add her again.  When I look at the payroll, I can only see one check each week for this employee.  How would I check to see if there is a paycheck hidden some where?  Thank you again.
