Just what we need. Another phone number formatter. What does this make? Eight for North American numbers?

No need to be snide Matt. Everyone is entitled to their take and to try their hand at things.

Neat bit there where a missing area code (often left out in legacy data and in fast data entry because it is always the same) gets interpolated into the phone number. Slick and just what I needed! thanks.

I appreciate it very much and it works great!!!

Matt I wish I was as smart as you, but I am not and so I appreciate help when I can get it. Please do not hack in my computer for saying that!

Thank You
