Circular reference issue

[Hdata]

Thanks in Advance!
I'm trying to create a formula at the table level which creates a circular reference problem that way I am doing it.
I am using two fields; acres and square feet. One acre = 43,560 sq. ft.
I would like to input the number of acres and get the number of sq. ft. calculated automatically. Also, when I input the number of sq. ft. I want the number of acres calculated automatically. Any suggestions?

Use three fields. One should be the authority, and maybe it should be hidden. The two fields you update are subservient fields, child fields. This will be easier in a form. A table doesn't allow you very much control.
