[Plugin: Visual Form Builder] Google Analytics Goal Tracking

Hello,

I am trying to add goal tracking to the submit button on the form. Can anyone offer tips on how to do this? I have read several articles on how to do this however I keep getting fatal errors when I try to add the:
onclick="_gaq.push(['_trackEvent', 'Button Clicks', 'Products', 'The blue button on the form page']);"

I was using this article (although most say the same)Tracking Clicks on a Link and Clicks on a Button

Any help would be Great!! Thanks!!

Oh and here is a link to the live form: http://www.sunshinejanitorialandcleaning.com/quote
