Adam,

   Thanks.

   I've modified my Dialog Box script.

   I'm not understanding why the var editor = Window_GetDialogArguments(window); portion of the script isn't recognized when I use rng = editor.selection.createRange();.

   The script generates a editor.selection is Null or not an object.

   I want to preserve the selected text if any has been selected, or use the .text property of the options collection for the selected option in a select.

   Here is the script:

 

  <script language="javascript" type="text/javascript">
   var editor = Window_GetDialogArguments(window);
   var selectedPage = document.getElementById('allPages');
   var selectedText = '';
   
   function button_click() {
    selectedText = getSelectedHTML();
    if(selectedText != '') {
     //do nothing
    }
    else {
     selectedText = selectedPage.options[selectedPage.selectedIndex].text;
    }
    editor.PasteHTML('<a href="http://cutesoft.net/websites/index.asp?dpt=<%=Request.QueryString("dpt")%>&pageID='+selectedPage.options[selectedPage.selectedIndex].value+'">'+selectedText+'</a>');
    window.close();
   }
   
   function Window_GetDialogArguments(win) {
    var top = win.top;
    var opener = top.opener;
    
    if(top.dialogArguments) {
     return top.dialogArguments;
    }
    
    if(opener == null) {
     return top.document._dialog_arguments;
    }
    
    return opener.document._dialog_arguments;
   }
   
   function getSelectedHTML() {
    var rng = null
    var html = '';
 
    if(document.selection && document.selection.createRange) {
     rng = editor.selection.createRange();
     html = rng.htmlText || "";
    }
    else if(window.getSelection) {
     rng = editor.getSelection();
 
     if(rng.rangeCount > 0 && window.XMLSerializer) {
      rng = rng.getRangeAt(0);
      html = new XMLSerializer().serializeToString(rng.cloneContents());
     }
    }
    
       return html;
     }
  </script>
