Test Page work in IE but not Firefox

I built the attached test page.  I thought it was working, but when I tries it in Firefox not all of it functions.  The favoite buttons don't work.  Here is the page
http://www.glassdivider.com/Wedding_test.html

Here is the script:

<script type="text/javascript">
function LGpic(id){
      var picid = "pic"+[id];
      var txtid = "txt"+[id];
      var image =document.getElementById(picid).src;
      var text =document.getElementById(txtid).innerHTML;
document.getElementById('Largepic').src = image;
document.getElementById('txtLP').innerHTML = text;
}
function fav1(){
      var bigtxt = document.getElementById('txtLP').innerHTML;
      var bigpic = document.getElementById('Largepic').src;
      document.getElementById('Favorite_pic1').src = bigpic;
      document.getElementById('ftxt1').innerHTML = bigtxt;
}
function fav2(){
      var bigtxt = document.getElementById('txtLP').innerHTML;
      var bigpic = document.getElementById('Largepic').src;
      document.getElementById('Favorite_pic2').src = bigpic;
      document.getElementById('ftxt2').innerHTML = bigtxt;
}
function fav3(){
      var bigtxt = document.getElementById('txtLP').innerHTML;
      var bigpic = document.getElementById('Largepic').src;
      document.getElementById('Favorite_pic3').src = bigpic;
      document.getElementById('ftxt3').innerHTML = bigtxt;
}
function fav4(){
      var bigtxt = document.getElementById('txtLP').innerHTML;
      var bigpic = document.getElementById('Largepic').src;
      document.getElementById('Favorite_pic4').src = bigpic;
      document.getElementById('ftxt4').innerHTML = bigtxt;
}
</script>

Thanks for the help.

please debug using FireBug...
Try to avoid document.getelementbyid and try using jquery for all DOM related activity.
Its tailor made for cross browser solutions....

here are the corrections to fav1:-

function fav1(){
      var bigtxt = document.getElementById('txtLP').innerHTML;
      var bigpic = document.getElementById('Largepic').src;
      document.getElementById('favorite_pic1').src = bigpic;
      document.getElementById('ftxt1').innerHTML = bigtxt;
}

marked bold is modified, letter f of favorite should be smaller.
Fire fox search is case sensitive..

Make the other changes accordingly...
but just try to use JQuery and be specific with case when you work in JS.
