I just made a small form in Excel with the intention of copying and pasting
it into an email message. The recipient would read it, then click on "reply"
and go down and complete the form. Everything works except I included a
control box where a check mark would appear when the box is selected by the
recipient. This box doesn't work at all. Does anyone know why?

Also, I am not too sure overall how to make up a form that I can use for
completion via email.
