Go to your Admin CP >> vBulletin Options >> vBulletin Options >> General Settings >> Add Template Name in HTML Comments. Tick this to Yes. vB will now put comments in the Source Code where each of your templates begin and end.

Rerun the Validator with the Show Source option selected. This will create links in the error messages that jump down the page to where your Source Code is being displayed, right to the line it detected the error on. Remember that it only detects the error in this vicinity. It could be that something before that is incorrect. You'll need to look around and possibly do some Google searches to understand what each means. Start with the top one first, as errors tend to cascade. Fixing one can fix a bunch below, or reveal others that the Vaildator couldn't previously detect.

You're fortunate, you only have 9 errors. When I started learning about Validation, I had over 600. At the very least, you can say that page is vaild when your done.
