Somehow adding to “Insert Into URL” posts are contradicting each other

Question

So it turns out I had a few unecessary variables in here.

I didn’t need to define formfield as a var because it’s unused. I defined it twice.
Because there are two functions sharing common variables, it’s best that I nest the window.send_to_editor within each of the click functions.

This is the final version of both the jQuery functions ( the source of the problem)

jQuery('#upload_doc_button').live('click', function() {

    window.send_to_editor = function(html) {
        var docurl = jQuery(html).attr('href');
      jQuery('#wpa_upload_doc').val(docurl);
        tb_remove();
    }

    tb_show('Upload Publication', 'media-upload.php?TB_iframe=1&width=640&height=263');
    return false;
}); 


jQuery('#upload_image_button').click(function() {

 window.send_to_editor = function(html) {
  imgurl = jQuery('img',html).attr('src');
  jQuery('#upload_image').val(imgurl);
  tb_remove();
 }

 tb_show('', 'media-upload.php?type=image&amp;TB_iframe=true');
 return false;
});
