I have a field that calculates the date into text:
1/2/2006 changes to January 2, 2006
easy enough, but there are instances where the day may not be available, generally because it was omitted from the document, so I need to be able to manually enter it as January _, 2006... I added a catch to the calc that if the left most character is an "*" then the calculation isn't activated and the "*" is automatically removed when printed.... ex: *January _, 2006
But I would rather do it differently. If I enter 1/_/2006 I get ? ?, ? is there any function that can look at the calc and see if it will fail instead of me using the "*" to force it not to calculate?
