Problems with two "when Green Flag clicked" scripts. A six line project that counts to 3 and plays a musical note three times. * What could possibly go wrong? * Green Flag to run the project. Green Flag to run the project again! The project always works, but it is a fluke! Here is a project with identical code that doesn't work at all! It plays 4 notes or none at all. https://scratch.mit.edu/projects/323749687/ This version of the program always works because the top "when Green Flag clicked" script always runs before the bottom script when we click the Green Flag. The top script is not run first because of its position in the editor. You can drag the two scripts up, down, left or right or put them on top of each other. The top script will still run first. In the other version of this project, the bottom "when Green Flag clicked" script always runs before the top script when we click the Green Flag.
