Report each step of Magento's One Page Checkout to Google Analytics

This code allows you to track each step of Magento's One Page Checkout in Google Analytics.

The code should be installed at the bottom of the /app/design/frontend/default/YOUR_TEMPLATE_NAME/template/checkout/onepage.phtml template file.

 <script type="text/javascript">
    // Report each step of the checkout process to Google Analytics
    Checkout.prototype.gotoSection = function(section) {
        try {
            pageTracker._trackPageview('<?php echo $this->getUrl('checkout/onepage') ?>' + section + '/');
        } catch(err) { }
    
        section = $('opc-'+section);
        section.addClassName('allow');
        this.accordion.openSection(section);
    };
</script>
 
Once installed, you can Create a Conversion Goal.
 
1. Goal Name: Successful Purchase
2. Active Goal: On
3. Goal Position: Set 1, Goal 1 (I didn't have other Goals, so this was the position I used.)
4. Goal Type: URL Destination
5. Match Type: Head Match
6. Goal URL: /checkout/onepage/success/
7. Create your Goal Funnels as follows;
 
Step 1: /checkout/onepage/
Step 2: /checkout/onepage/billing/
Step 3: /checkout/onepage/shipping/
Step 4: /checkout/onepage/shipping_method/
Step 5: /checkout/onepage/payment/
Step 6: /checkout/onepage/review/
