HTML5 Validator - 'Missing Primary asset check'

Hi All,

Thanks for reading this! Am going crazy trying to figure it out.

When running my zipped HTML5 file through the HTML5 Validator, it keeps coming up with "Missing primary asset check".

I've read through many other discussions and googled the hell out of it but no solution has worked so far.

(I solved a few other errors I had this way)

I've screenshot the code below, and if anyone has a solution, I'd be forever grateful.
