Html validator errors not found?

Hello i put this page trough html validator…
http://apdinnovate.com/contact-us/

but can’t find where the errors are. other pages are fine…this one went belly up.
just looking at it some div is missing but went over my code & can’t find it.
I also simplified it for this custom page and am using contact form 7
Thx

When your submitting a page for validation, click on “More Options” and make sure that “Show Source” and “Show Outline” are selected. Then at the bottom of the output of the validation it’ll show you the outline with line numbers

Thanks Space! That helped.
