That's what I did. In the value box, I typed
[Field1]&[Field2]

Then I tried [Subject]=[Field1]&[Field2]

And I tried =[Field1]&[Field2]

None worked.

I also tried changing the settings on the value tab to set the initial value
of this field to, and the different radial buttons: calculate automatically,
and calculate when I compose a new form

This formula would combine the values from two custom fields on the item:

[Field1] & " - " & [Field2]

Sue, I must be doing something wrong. Can you tell me the syntax you used to
make that work? Thanks so much. Michelle

You can't change the data type for any standard field. What you can do is set a formula for the control that shows the Subject property.

I want the subject of a custom form to be a combination type. How do I (can
I) change the field type to combination, so that I can enter the formula?

Thanks
