Super amateur question follow-up (URL help needed)

Question

I neglected to say in a previous post that I actually have five images in the flash animation that need to link to web pages.
I duplicated the code that worked on one image. Now I get an error saying there are duplicate function definitions. Here is the code I have added which I hoped would work for three images. It doesn't. Your help is greatly appreciated.
bfcSyringe_mc.addEventListener(MouseEvent.CLICK,onClick);
function onClick(evt:Event):void {
    var targetURL:URLRequest = new URLRequest("http://hodentalcompany.com/pages/syringe.html");
    navigateToURL(targetURL, "_self");
fpr_mc.addEventListener(MouseEvent.CLICK,onClick);
function onClick(evt:Event):void {
    var targetURL:URLRequest = new URLRequest("http://hodentalcompany.com/pages/fpr.html");
    navigateToURL(targetURL, "_self");
sandTrap_mc.addEventListener(MouseEvent.CLICK,onClick);
function onClick(evt:Event):void {
    var targetURL:URLRequest = new URLRequest("http://hodentalcompany.com/pages/sand.html");
    navigateToURL(targetURL, "_self");

Answer 1

And, for Funky Soul's solution, I used this code:
bfcSyringe_mc.addEventListener(MouseEvent.CLICK,onClick);
bfcSyringe_mc.name = "bfc";
fpr_mc.addEventListener(MouseEvent.CLICK,onClick);
fpr_mc.name = "fpr";
sandTrap_mc.addEventListener(MouseEvent.CLICK,onClick);
sandTrap_mc.name = "sand";
function onClick(evt:Event):void {
switch(e.target.name)
case "bfc":
    navigateToURL(new URLRequest("http://hodentalcompany.com/pages/syringe.html"), "_blank");
    break;
case "fpr":
    navigateToURL(new URLRequest("http://hodentalcompany.com/pages/fpr.html"), "_blank");
    break;
case "sand":
    navigateToURL(new URLRequest("http://hodentalcompany.com/pages/sand.html"). "_blank");
    break;
And got this error:
1084: Syntax error: expecting identifier before _blank.
