        FragmentManager fm = getSupportFragmentManager();
        dialogfragment testDialog = new dialogfragment();

        end
        local i = 1
      while i
                local randNum = math.random (1, maxRandom) 
                local flagNew = false 
                    for j = 1 , randCount do 
                         if randomArray[j]==randNum then 
                            flagNew = true
