Without being able to see your code and the errors, I don't think anyone can help you one way or the other.
Though, I looked through your past posts and found americanindustrialinc.com/wp. Is this the site you're trying to validate?
The validator is right. A charset on a script tag is only meaningful if you're loading an external script. That's not the case here.
...industries that include: <strong>aerospace, automotive production, food processing, government agencies, steel production, high-tech military equipment and many more industrial product manufacturing industries.<strong></p>
The validator is right. It looks like you meant to write a closing </strong> but instead you wrote an opening <strong>.
And here you're missing a quote.
I strongly suggest you look back through the validator's errors under the assumption that the validator is right (because it probably is).
