[HTML]<html>
<head>
<script type="text/javascript">
function check($char, obj){
if (obj.value > 100.0)
{
return false;
}
if (obj.value.leng th == 0 || obj.value.lengt h == 1)

if(($char >= 48 && $char <= 57)||($char >= 96 && $char <= 105) || $char == 190 || $char == 8 || $char == 9 || $char == 46 || $char == 13 || $char == 9 || $char == 35 || $char == 36 || $char == 37 || $char == 39 || $char == 110)
{
return true;
