Access 2003 – Feild size of Textbox

I have a two qustions.

1. I have a 11 digit number that I would like to desplay in 3 different textboxes on a form.
Box 1 = First 4 digets
Box 2 = Next 5 digits
Box 3 = Last 2 digits

Anyone have any ideas or thoughts?

2. Can you set up a text box to only desplay 5 digets that are seperated by “-“, simmilar to how Social Security numbers are seperared. The 11 digit number is formatted like this “2H03-55340-01”, I would like to only dispaly the “55340”.
