[Plugin: jQuery Collapse-O-Matic] Single Hash Tag in Url

I was getting a jquery error using this plugin in all browsers if there was a single hash tag in the url. I traced the error to line 180 in collapse.js, so I added a simple if statement to check to make sure that the url fragment contained more than just the hash tag and that fixed it. Hope this helps someone else!

var myFile = document.location.toString();
if (myFile.match('#')) { // the URL contains an anchor
    // click the navigation item corresponding to the anchor
    var myAnchor = '#' + myFile.split('#')[1];
    if (myAnchor != '#') {
        jQuery(myAnchor).click();
    }
}
