No Impure (Blue) Calculate Direction Function

Hello, just as the title says, I am stuck at the point where I try to get the function for “Calculate Direction” but it is a pure (green) function and not an impure (blue) function with the execution pins/nodes.

Will the pure function still work as intended for the lesson “Blendspaces” ? … or am I missing something obvious?

Using 4.26

Found solution under different thread.
