Please excuse me as I am new at this, but I'll explain what I'm doing as best
I can.

I created a form in excel that does the following:

User clicks the 'Submit' button.
The form is automatically attached to an Outlook e-mail and sent to a
distribution list.
Users on the Distribution list receive the e-mail and open the attachment.
At the bottom of the form there is another command button for the "Approval"
section. However, when the attachment is opened, the second command button
doesn't work.

How do I fix this?

Thanks!
