Trying to put a calculated field on a form

[NOVAmichelle]

I have a master form that has totals by month for various things. I want to create an unbound field on this form which will total some of the fields. Please help.
Also, I just realized that my fields are text. Should I change them to number fields?

=Sum(Val(FieldName)) or =Val(Field1) + Val(Field2) + Val(Field3)...etc

Usually it's a good idea to use number fields when it's a number, but if you need it as text for one reason or another, leave it and use Val() to convert it to number.
