I tried my hand at designing an Outlook Form. The most frustrating thing for noobs seems to be that when they send the form, it appears blank. For me, the fix wasn't in the first page of Google results. Here's where I got my fix: http://www.slipstick.com/developer/designing-custom-forms/
The problem was the Page setting. By default, the layout for Compose (when entering data into the form) and Reading it (after being sent) are separate. To fix this, uncheck "Separate Read Layout". This will cause the form to be displayed even after it is sent.
