Yeah what it says in the title. I'm guessing this was an error and we don't want constant DIRECTION_TO_FRAME to change to a variable right?
I just checked the lesson. I think the wording can be confusing, the intention of this second replace was in the sense "erase the keyword const before the speed variable and type var instead."
Yeah that's what I did but as we were still thinking replace as the handy new tool then I first presumed to use it rather than do it manually. Just a point of potential student error there to consider.
