Locking a field
Here is my layout
Month (date type) hours hourly rate total billable program
say for month date = 01/12/2009
but after this date 29/12/2009 I no longer what people to play with these fields. This would go for any month and any year between the dates of the 1st of the month and the 29th of every month
I have a way to lock as soon as a date is entered but this will need to be changed through the month.
I just don't want people going back and playing with this to screw the totals for that month.
