#!/bin/bash
choice=$(kdialog --menu "CHOOSE
ONE:" 1 "RED" 2 "YELLOW" 3 "GREEN");

if  [ "$?" = 0 ]; then
	if  [ "$choice" = 1 ]; then
		kdialog --msgbox "YOU CHOSE RED";
	elif [ "$choice" = 2 ]; then
		kdialog --msgbox "YOU CHOSE YELLOW";
	elif [ "$choice" = 3 ]; then

	else
		kdialog --error "ERROR";
	fi;
elif [ "$?" = 1 ];then
	kdialog --sorry "YOU CHOSE CANCEL" | exec
else
