Newbee Needs Help with Validation of Site

Hi, I went to the validation site for my web site and received this report -

The website pages are not validated as per the W3C standard. It is suggested here to get the pages validated for html as per the W3C standard.

http://validator.w3.org/check?uri=ht...Inline&group=0

Am I correct to assume that what I need to do is correct the code for each line of errors that appears on this report?

If so, I had this validation done but I do not think it is what I need to validate or correct the site since it is just the home page that the coding was done on....Page where code was entered - just the home page:
http://www.nextgi.com/client/savethedate/

which resulted in this validation:

Validation:

re: Newbee Needs Help with Validation of Site

Yes, each line needs to be corrected, however, many of the errors are typographical. XHTML is case sensitive so <p> followed by </P> will be flagged as an error. Also, there is no such thing as 'language =Javascript' and end tags must be /> with the slash.

I'll bet flash is throwing some of those errors in. There's a valid way to do it but I'd have to look it up.

Several of those errors may be fixed in one swoop by just fixing one of those errors.
