Robot tip (Compare and fix one thing): Run it, spot what went wrong, find the buggy line, fix one thing, test again. Wrong side → a turn is the wrong way. Too far or too short → a forward number is wrong. A shape that does not close → the turn should be 360 ÷ sides; a gap → the repeat number should equal the sides.
