I've been editing forms using Livecycle.  A validation pattern within one of the fields is becoming jumbled.  It's supposed to show a numeric code when too many numbers are typed into the field so the employee knows too many digits were typed and can correct the error.  The validation pattern is reading the too many digit error, but has also started not accepting certain patterns of numbers.  I've tried several different things to correct this issue.  What can be done?  I know deleting the field will take care of it, but we would ultimately like the validation pattern to work correctly.  I was not the one who created the forms originally and am an amateur when it comes to Livecycle.  I'm not even 100% certain how to add a validation pattern to a new field if I were to delete it and start fresh.  What can I do?
