Allow an option to set fields to only allow alpha characters (essentially to NOT allow numeric characters). For example, we have a field for prefix (Mr., Mrs., military prefixes, etc. - too many for a drop down box), there have been about half a dozen parents entering their phone number in this field. I THINK it might be autofill reading "prefix" and relating it to the prefix of a phone number. If we did not allow numeric characters, this will flag the parent that the field needs to be corrected.
