Google adwords conversion tracking integration in joomla php file

I am trying to include a piece of code from Google Conversion Tracking into my business contact from which is based on Jomla. The code should be integrated once the Thank you message appears but unfortunately I am very unexperienced with javascript and php. Could someone please give me a hand having these two pieces of code combined?

Thank you very much, James

Code Jomla

            //<![CDATA[

        window.addEvent('load', function() {

            changeCaptcha(".$this->profile->id.",0);\n".($use_ajax?"resetSubmit(".$this->profile->id.");\n":"")."

            if($(typeof SqueezeBox!='undefined' && 'system-message')) {

                SqueezeBox.initialize();

                SqueezeBox.open($('system-message'), {开发者_JAVA技巧

                    handler: 'adopt',

                    size: {x: $('system-message').offsetWidth+30, y: $('system-message').offsetHeight+30}

                });

            }

        });
