onclick event within the functions.php file

I am building some text output for a specific page using my theme’s functions.php file – the file that everyone uses.

I have a function that echo’s out the details from a few functions to the screen, and this is one of them.

One of these functions sends the text to the calling function, I have this (shortened for easy reading);

function btm_ca_101_text_before_category_step1() {
	return "blah blah...
		<a href='http://www.blahblahblah.com/pdffile.pdf' target='_blank' onclick='_gaq.push(['_trackEvent','Download','PDF',this.href]);' >Click Here to Download the Top Ten Guide (PDF).</a>
		blah blah blah";
}

The problem is when it’s actually echoed out into html, the web page shows;

<a _trackevent','download','pdf',this.href]);'="" onclick="_gaq.push([" target="_blank" href="http://www.blahblahblah.com/pdffile.pdf">Click Here to Download the Top Ten Guide (PDF).</a>

I can’t figure out why everythign is rearranged.
