Yes it is important. In my case, the form was used as a registration for Soccer Tryouts. There are several people (each coach at each age level) who look over and download the database so the data itself must be correct BEFORE it is downloaded.
You cannot believe the amount of people who screw up their kids names and birthdates.
That Birthdate HAS TO BE CORRECT or the child will be put into the wrong group when they show up. There is a confirmation email that goes out for them to "double check" the submitted information and that is where the mistake is caught. I then get the email, have to copy the information down, delete the entry and enter it myself.
I have tested it on my own MYSQL database and if used that way (although not as nice as s-drive) i can at least edit the entry that was "fat fingered" and move on. A much easier process for the "web guy".
i hope you can make that change in the future.
