Need help editing the code

The theme uses boxes, one of them is for price plans. The link to purchase the price plan is a button. The code that creates the button is:

PHP Code:

---

( '' != $button_text ? do_shortcode( "[et_lb_button size='medium' align='center' url='" . esc_url( $button_url ) . "' color='{$button_color}']{$button_text}[/et_lb_button]" ) : '' ) .

This code outputs a linked button with the link looking like this:

PHP Code:

---

<a href="http://businesswebsitedev.com/clients/cart.php?a=add&pid=1"> 


---

I need you to edit the code so that it outputs a linked button with the link looking like this:

PHP Code:

---

<a href="http://businesswebsitedev.com/clients/cart.php?a=add&pid=1" onclick="_gaq.push(['_link', 'http://couponcodeelite.com']);return false;">

I am using google analytics and need the onclick function added to the link so that it works properly. The problem is that I do not know how to edit the coding so that it will output the link like I have shown you above.

Thank you

Can you try to stack those codes in the onclick event like this:

Code:

---

    <a href="javascript:void(0);" onclick="loadevent('http://www.EXAMPLESITE.com/course/4105/register.asp');pageTracker._link('http://www.EXAMPLESITE.com/course/4105/register.asp'); return false;">Register</a>

It will be able to run all of the commands as long as they're separated by semi-colons.
