I am trying to add a new field in my custom contact form and it is giving me
trouble. I have added a few new fields already, using the "yes or no" format,
and those come out fine, but when I try to add an extra one, using the same
format, it doesn't come out correctly. It gives a text box instead of a check
box.

How can I get it to come out as a check box, like the others?
