I have 2 Formatted Short Date Fields. Start Date and End Date. The Users can pick any Year or any Month but the Start Day must be the first day of the Month and the End Day must be the Last day of the Month.
And the End Date has to be after the start date. (I can handle this)
The Tables are SQL but the Form that the Users edit is Access. I was thinking of adding code to the Close button to verify this data before allowing them to Close. If it is not correct I will display an error message. I can handle the error message but how do I do the validations for what day of the month they entered?
