"Create a project that uses a variable to decide when something happens.." I wanted to revisit a previous project to make it work better. I added an introduction screen to choose operation and difficulty level. I learned that the "glide" command would not complete if it was started within a "when i receive the message ____" block, and the same broadcast was issued again. Interesting timing issue with scratch. I got around it by using separate broadcast messages.
