thankyou message doesn't show up.

I’ve added an eForm and the thankyou message doesn’t show up.

I created the chunk and properly named it.

My tag is below. What am I doing wrong? I am 2 hours on this problem now!

[!eForm? &formid=`ContactForm` &to=`[email protected]` &tpl=`ContactForm` &report=`ContactReport` &thankyou=`ContactThanks` &subject=`Web site feedback`!]

Sounds like it could be a server issue... check this out:
