Button as a fake link for a Google Analytics funnel

I'm trying to set up a funnel that has a final step of clicking on a button and downloading a document. Since I can't track the button, I was hoping to set up a fake link that doesn't redirect the user anywhere but allows Google Analytics to see how many people clicked on the button.

What I have is this Javascript piece of code but when it gives me an error:

<a href=”/goal/example” onclick=”javascript:pageTracker._trackPageview (‘example’);”target=”blank”>

Or, if this doesn't work at all, is there any other way to add a button to my funnel?

Thanks!
