Problems with \_gaq.push and \_trackEvent?
1. Check JavaScript/Firebug console for errors.
2. Check that all values are in supported format, e.g. [the value parameter must be an integer](https://developers.google.com/analytics/devguides/collection/gajs/eventTrackerGuide)
3. Use the queue to postpone or perform actions in sequence:
```javascript
_gaq.push(['_trackEvent',...])
_gaq.push(function() {
document.location = 'http://google.com'
})
```
