We have all been there and done that.
Restarting is the best lesson!
Well - i've checked the code with a highlighter and the divs are all ok actually - so i'm sumbitting my problem with images and a link to the page on a test site I have...
Now there are a few issues here.
The first is that in Dreamweaver everything looks fine - the stylesheets are applying but wne I go to live view OR view in any browser then the styles are lost.
Second issue is that the footer bar has box clear floats which is OK in dreamweaver until it is previewed.
Third issue - is that in dreamweaver the wrapper is not centred of the body - it is in the stylesheets to auto margins, however it DOES work when live.
I'm scratching my head here - it's 3.30 am and I need a coffee!

Thanks in advance for any and all feedback
1. Change line 68 to read CallbackPanel (with lower case L) not CallbackPane1 (with a number one)
2. Add <br style="clear:both;" /> to line 103
3. Don't take notice of Design view in DW
