formatting output in the report

[cancer2006]

I want to adjust the formatting of the telephone number. as
"123-456-7890" right now it is displaying as 1234567890.

I am using Access97. my database field name is "Best time to call" data type text.

How do I change the formatting? Do I need to write a VB code or go into expression builder.

Thanks.

You should be able to go into the field's properties and click on "input mask". There is a wizard to walk you through some of the steps
