Perl CGI print statement

I currently have the following print statement in a cgi script working fine:

if (!$Product_Name){
$Product_Name=" ";
print "<td><A href=\"parts.cgi?RecordNumber=$loopsaround\">$Product_Name</a></td>\n";}
else{
print "<td><A href=\"parts.cgi?RecordNumber=$loopsaround\">$Product_Name</a></td>\n";}

How do I incorporate the following into the <a href> as an onclick event?  When I try to put it in it errors out I am assuming due to some sort of issue with the syntax?

<a href="#" onClick="opennewsletter('parts.cgi?RecordNumber=$loopsaround'); return false">$Product_Name</a>Start Free Trial
