Our Dutch license plates do exist of numbers and letters. These groups of numbers or letters are separated from each other by dashes. If I enter a license plate like 12ABC3, I would like it to be formatted 12-ABC-3. Combinations like 1ABC23 (1-ABC-23) or 12AB34 (12-AB-34) are possible as well. I cannot figure out yet how to accomplish this. Anyone an idea? Your time is much appreciated!
