I have a table with the following fields to monitor Employee leave within my organization:
ID, Employee,dateLeaveStart, DateLeaveFinish, Days, LeaveType, [attachememt]
When I enter new records (i'm using the datasheet view for now), I'd like to restrict entering new records where EMPLOYEE and (dateLeaveStart OR DateLeaveFinish) match.
The idea is that if I have already marked one employee as sick for a particular day (or range of dates), I would not be able to enter another record for the same dates.
appreciate any help you can give!
