Javascript Keys routine doesn't work in FireFox

Hi All

I have a JS routine to prohibit users from entering a range of chars in a
textbox and although this works perfectly in IE x, in the latest version of
Firefox it appears to be blocking keys that I want to allow. The routine
sort of still works, but its as if the mapping of the keys is worked out
completely differently. I thought the key maps would be universal.

My code is as follows:

HTML:

<INPUT TYPE="TEXT" NAME="qty" SIZE=5 MAXLENGTH=12 CLASS='FormQtyBox'
VALUE="1" onKeyDown='return CheckQtyEntry(event)' onKeydown='return
CheckQtyEntry(event)'>

JS:

function CheckQtyEntry(e) {
 var key = (navigator.appName == "Netscape") ? e.which : e.keyCode;
 var shiftcheck = (navigator.appName == "Netscape") ? e.SHIFT_MASK :
event.shiftKey;

 if (shiftcheck) {
  if (key == 8 || key == 9 || key == 46 || (key > 95 && key < 106)) {
   return true;
  }
  else {
   return false;
  }
 }
 else {
  if (key == 8 || key == 9 || key == 46 || (key > 36 && key < 41) ||
     (key > 47 && key < 58) || (key > 95 && key < 106)) {
   return true;
  }
  else {
   return false;
  }
 }
}

This routine basically forces the user to only enter numbers from either the
main keyboard set or the numeric keypad. Like I said before it works fine
in IE, but the key codes for Firefox seem to be different.

Any ideas as to what the solution is?

Thanks
