hi,

*javascript function :

function isNumber(obj) {
        var len  = obj.value.length;
        var lastChar = obj.value.charAt(len-1);
        if( lastChar != '0' && lastChar != '1' && lastChar != '2' &&
lastChar
!= '3' && lastChar != '4' &&


        lastChar != '5' && lastChar != '6' && lastChar != '7' && lastChar !=
'8' && lastChar != '9' ) {
                obj.value = obj.value.substring(0, len-1);

        }

}
