  Note this (immediately after the body tag):

<SCRIPT LANGUAGE="JavaScript">
function DrvAdd()
{
>    A = parseInt(document.form.INTERLT100.value);
>    B 
parseInt(document.form.INTERLT100.value);//Are you
sure?
>    C = (A+B);
>    document.form.TOT_DRS.value = C
/* You can write simply:
  TOT_DRS.value = parseInt(INTERLT100.value) +
parseInt(INTERLT100.value);
  //(Of course, supposing that you have the
appropriate text boxes)
*/  
}
</SCRIPT>
  You may call the function on losing focus either on
text1, either on text2
<INPUT TYPE="text" name="INTERLT100"
onblur="DrvAdd()">

  Good luck!
