Dear W3C,
 
I receive different responses from W3C's validation service depending on which method I choose to validate my HTML code.
 
If I use the "Validate by File Upload" I receive:
This document was Tentatively checked as HTML 4.01 Transitional
Result:
 Tentatively passed, 2 warning(s) 
 

 
If I use "Validate by Direct Input" I receive:
This document was successfully checked as HTML 4.01 Transitional!
Result:
 Passed 
 

I have attached the file I am validating. Please let me know which results are the ones I should consider correct. I am an online student at the University of Phoenix, and your results as affecting my grades. My instructor, who is checking my work by using your "Validate by File Upload" method, receives 2 warning messages on my HTML code, and is penalizing me points based on these results. 

I am checking my work by using your "Validate by Direct Input" method, which tells me I have no errors or warnings, in fact, that my code has "passed" and I can include a W3C icon on my Web page because of this high-level result. 

Could you please explain to me why we receive two different results when checking exactly the same HTML code?
 

Thank you,

Jerry Salvatore
