I only know of http://jigsaw.w3.org/css-validator/ but I can't imagine that there's anything out there to automatically fix your errors, that would require human interaction
Validate here>>http://www.w3schools.com/site/site_validate.asp But nothing will fix your errors -- if there is an error how do you expect the software the know what you wanted to do?
Try sitepoint or google for css forums and get someone to fix it for you, shouldn't be too hard, offer them $20 or something.
