Finding a cell that has been badly entered

Hello everyone,

In my pdf form (adobe acrobat 9), I have several cells that ask for a date. I order for all the dates to be written the same way, I have put a validation model in place. The problem is that went people want to send the form and that one of those date cells is not properly entered, a error message appears but does not say where in the document (17 pages) the date cell has been wrongly entered. What can I do about this?

Thanks for your help
