Swift playground won't moveforward

I'm working through the lessons. In Treasure Hunt page 1, I entered the following:

func movethentoggle() {

moveForward()

moveForward()

toggleSwitch()

}

func turnaroundforward(){turnLeft()

turnLeft()

moveForward()

}

movethentoggle()

turnaroundforward()

IT won't move forward the second time, so it can't toggle the switch. Instead, it skips down and turns left, then steps left and toggles! Then it hangs up.

DOes anyone one know why it can't step forward a second time, as it has done in previous lessons?

thanks for th help.
