The first three cells, all initialization cells, each contain a simple one-liner, for example: dist[p1_, p2_] := Norm[p1 - p2] When I evaluate any of these cells, it appears to define the function, but when I try (in a second, new notebook window) to evaluate the function (e.g., to evaluate "dist[4.5]}), the function is undefined. It is blue i the second window, even though it is black in the first window.
But If I type "dist[4,5]" in the demonstration project window itself, all works as expected.
The demo project does not appear to be a package; 'dist' does not seem to be private. What am I missing?
