I need help to implement Modernizr.

I have posted a test at http://www.craigwebbart.com/mmw/modernizr-test.htm

The scripts that I want Modernizr to load are

css3-multi-column.js
respond.min.js
selectivizr-min.js

They are also commented-out at the bottom of the Test HTML.

I can see that jQuery and Modernizr are loading. I can see that the yep/nope JavaScript that I created is not working. Is it because these polyfills are not needed in my browser? The code appears to have a parsing error but I don't know why.

I also do not know if these are the appropriate tests to load the polyfills as needed or if they are well-formed.

Here is the yep/nope test script that I made. Please help me to improve this script and point out any other errors that you see. Also I am interested to learn of any resource that lists unified data for
modernizr test / polyfill / yep/nope test script:

Code:
<script type="text/javascript">
// Give Modernizr.load a string, an object, or an array of strings and objects
Modernizr.load([
  // Presentational polyfills
  {
    // Logical list of things we would normally need
    test : Modernizr.csscolumns(columnCount),
    // Modernizr.load loads css and javascript by default
    nope : ['js/master-scripts/css3-multi-column.js']
  },
test : Modernizr.mq('@media only screen and (width)'),
nope : ['js/master-scripts/respond.min.js']
},
test : Modernizr.generatedcontent(),
nope : ['js/master-scripts/respond.min.js']
}
);
</script>

THANKS!
