End of semantic HTML section project - resume

Hi there everyone,

I put the above code in the W3C validator, and got this error message:

Error: Start tag article seen in table.

From line 63, column 28; to line 64, column 47

<table>↩ <article id="uphealth">↩

Would anybody have any suggestions as to how to fix this? And provide me with an explanation as to what I should be doing in terms of and tags?
