Hello,

I have an existing asp.net page that asks for a customer's US phone number. Unfortunately, the field is set up to only accept entries in an unbroken number string, i.e.

6178899923

instead of

617-889-9923 or (617) 889-9923

How might I set up the field to accept phone numbers in one of these formats? I don't care as much how the number is stored in SQL, rather I want to make it easier for the customer. The unbroken string format is not familiar to a typical US user, and the form currently returns an error if dashes or brackets are used. For reference:

<code><tr>
                  <td width="110" class="content"> Phone
                  </td>
                  <td><input name="sphone" type="text" id="sphone" size="20" maxlength="15" style='BACKGROUND-COLOR: lavender' value='<%=sphone%>' /></td>
                </tr></code>

Thank you very much.
