E-mail a friend function not working

[dhutto]

I'm trying to get the 'send to a friend' function to work on a classified ads site I'm putting up. Below is a section of the php code in the templates section of the script's admin panel that I'm pretty sure is what is used for the button:

<td class="textbold"><a class="plain" href="{{SITE_URL}}/report.php?aid=$ClassifiedInfo->siteid">$ReportAd</a><br /><a class="plain" href="javascript:sendFriend($ClassifiedInfo->siteid);">$SendToFriend</a></td>
</tr>

This is the template code it's supposed to bring up:

                    <tr>
                      <td><table class="box_border" border="0" cellpadding="0" cellspacing="1">
                          <tr>
                            <td valign="top" style="background-color:#ffffff"><table border="0" cellpadding="0" cellspacing="0" style="width:100%">
                                <tr>
                                  <td><img src="{{SITE_URL_LANG}}/images/spacer.gif" width="10" height="7" /></td>
                                </tr>
                                    <tr>
                                      <td align="center"><h2>SEND TO FRIEND</h2></td>
                                    </tr>
									<tr>
                                      <td>$msg&nbsp;</td>
                                    </tr>
                                    <tr>
                                      <td><table style="width:70%" border="0" align="center" cellpadding="0" cellspacing="0">
                                        <tr>
                                          <td colspan="2"><img src="{{SITE_URL_LANG}}/images/spacer.gif" width="100" height="2"></td>
                                        </tr>
                                        <tr>
                                          <td>

But I keep getting a popup window back to the same page with an 'undefined' in the url:

http://www.stokup{dot}com/listing-3/Gears%20of%20War.html/undefined/undefined/sendMail.php?aid=3

The link I click to get there is the send to a friend at the bottom of:

http://www.stokup{dot}com/listing-3/Gears%20of%20War.html

Is there something I'm not seeing in the code that is linking to the wrong page somehow?

So, what you're saying is that the broken URL is generated by the JavaScript "sendFriend()" function that you haven't shown us? "undefined" is JavaScript's string representation of an undefined variable.

Below is a portion of the only JavaScript file I see with a reference to "sendFriend()"(I stopped after that particular portion). The only other JS files I see are "jsfunc" and "jsinstall", and I didn't see any reference in those.

//<!--

function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a)&&x.oSrc;i++) x.src=x.oSrc;
}

function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a.indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a;}}
}

function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers.document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}

function openWin(URL) {
aWindow=window.open(URL,"New","toolbar=no,width=600,height=640,status=no,scrollbars=1,menubars=no");
}

function sendFriend(aid){
root = window.location.href.replace("http://", "").split("/");
root = !root[2]?"http://"+ root[0] +"":"http://"+ root[0] +"/"+ root[1] +"/"+ root[2] +"/"+ root[3] +"/"+ root[4] +"/";

window.open(root+'sendMail.php?aid='+aid,'Sendmail','toolbar=0,scrollbars=1,location=no,statusbar=0,menubar=0,resizable=1,height=420,width=565,top=10,left=10');

}

Is there supposed to be a particular address in ("http://",""), and if so would it be the page that is used for the item being displayed, in this case being listing.php? I'm trying this now, but if it isn't what's wrong what do you think is, or is this the right JS file I need to edit?
