I used the W3C markup and validation service for http://www.wasmundbindery.com
and got this reply back. I don't understand what it means or how to fix it.
The DOCTYPE Declaration in your document was not recognized. This probably
means that the Formal Public Identifier contains a spelling error, or that the
Declaration is not using correct syntax. Validation has been performed using a
default "fallback" Document Type Definition that closely resembles HTML 4.01
Transitional, but the document will not be Valid until you have corrected the
problem with the DOCTYPE Declaration.
This page is not Valid HTML 4.01 Transitional!
Below are the results of attempting to parse this document with an SGML parser.
Line 1, column 0: no document type declaration; implying "<!DOCTYPE HTML
