Need help with a line in CS3 scripting

Hi all scripters,

I have this script for InDesign CS3:

if (app.documents.length != 0){
   var MY_DOC = app.activeDocument;
   var myLinks = MY_DOC.links;  
  
   var thePageNames = new Array();
   
   for (var i = 0 ; i <= (myLinks.length - 1); i++){
    
     if(myLinks.status == LinkStatus.LINK_MISSING || myLinks.status == LinkStatus.LINK_OUT_OF_DATE && myLinks.parent.parent.itemLayer.visible== true){  
  try{
  thePageName = myLinks.parent.documentOffset;
  } catch (e) { 
    
            continue; // must be on Pasteboard so ignore 
       }   
   
        thePageNames[thePageName] = 0 
     }   
   }    
     if (thePageNames.length == 0) {   
   
  } else{   
    
        var s = "";
     for (i in thePageNames){
   
       s = s + app.documents[0].pages[Number(i) - 1].name + ", ";
    
    }    
        
  s = s.substring(0,s.length - 2);    
       
  if(!confirm("Missing or not updated links in document - continue?")) 
            exit();   
    
   } 
}

When I run it nothing happens BUT if i change to this in line 28:

     if (thePageNames.length !== 0)

{  

and run the script again I get the confirm text from line 43 all the time even thoe there is no links in the document - what am I missing?

It works perfectly when I run this almost similar script for the overset text:

if (app.documents.length != 0){  
  
   var myFrames = app.activeDocument.textFrames;  
  
   var thePageNames = new Array();  
  
   for (var j = 0 ; j <= (myFrames.length - 1); j++) {  
  
     if(myFrames.overflows && myFrames.itemLayer.visible == true){  
  
       try { 
  
         thePageName = myFrames.parent.documentOffset; 
  
       } catch (e) {  
  
         continue; // must be on Pasteboard so ignore 
  
       } 
  
       thePageNames[thePageName] = 1  
  
     }  
  
   }  
   if (thePageNames.length == 0) {   
   
   
   } else{   
       var s = "";  
  
     for (i in thePageNames) {   
  
       s = s + app.documents[0].pages[Number(i) - 1].name + ", ";  
  
     }  
  
     s = s.substring(0,s.length - 2);  
  
     if(!confirm("overset text inside the document frame - continue?"))
     exit();
  
   } 
}
