I am having a problem with 2006 in the telephone field. I need to have the field default to United States (1); however, it may show another country or some other item from a totally different drop down window. I have not been able to find a procedure to set the United States as the default setting.
I am not a user of 2006, but I think all you have to do is go to define fields, you should find a field called default values, Type in United States and every new record created will have the US listed, then just override as needed.
I don't do any business outside of the states so I took that field out of my layout.
