Check only ONE box

[Emily Sue]

I want to give users options from which to select the ONE that best suits
their needs. I'm using checkboxes before each option. I've placed the
checkboxes/options in their own section in my form. How can restrict the
section to allow the user to only check one box?

Add a macro to run on exit from the field: if the box is checked, then
UNcheck all the others.
