Autofill phone number

				
'**************************************
' Name: Autofill phone number
' Description:I got sick of all the code snippets for filling in the "(",")", and "-" in phone numbers because in none of them could you use the backspace key if you made a mistake (They'd fill the backspaced entry out and you'd be back where ouy started)
' By: James Fitch
'
' Assumes:Doesn't seem to work on older versions of netscape. Don't know why, and haven't spent time trying to fix it.
Also, this keeps the raw phone number in a hidden field for form submission so that you can pick it up either way on the other end.
