6. Inside the repeat put another x/y block. In the x input connect a xcor block which can be found under the turtle. In the y input connect a loudness block that can be found under the wire symbol.
7. Then have a blank block. This block can be found under the repeat symbol.
8. Connect yet another x/y block. In the x input connect a + block. This block will be found under the 123+-= symbol.For the top value on the + block connect a xcor block. For the bottom value connect a number block with a 1.
9. For the y value on the x/y block connect s ycor block. Your blocks should look like this:
