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);

	}
