Hi everyone. I'm in trouble with postal code. The problem is that the mask of code is 00-000 and in base i've field number(5). The result I desire is to have interface human friendly to make user unable put code with mask for example 0-0000 or 000-0 or 000-00, just 00-000. I thought about two boxes one for 00 and second for 000. Second functionality that relates to the problem is presentation, if the solution is based on two fields/columns there probably will be needed concatenation. But in my opinion atomizing code that there would be 2 collumns [00] and [000] is probably bad solution. The target is to show on repports properely [00-000] and create interface in form to fill it with cone in the [00-000] format, display in repports in format [00-000] and of course save to the base and load. If somebody has idea how to resolve the problem, please write it down
