Second Kithmaze Indentation (Python)

In the Python campaign, during the second Kithmaze level, you have to use a while true loop in order to complete the maze in less than six statements. Every time I try to enter in the loop, it gives me the error of “Too much indentation at the beginning of this line”. Here is what it looks like
(four spaces)hero.moveRight()
(four spaces)hero.moveUp()

I’ve tried using both space button four times as well as the Tab button and I keep getting the same error. Can somebody help me out?

hero.moveDown() ?

All four move commands should be tabbed in so that they’re all in the while loop.
