Please help with codepen

Dear members, I am learning bootstrap studio and cannot understand one thing. I try to use codepen resources by implementing code into the bootstrap project. When I edit html and css everything is working fine, however when I place js. file into the project and paste the code, nothing happens. Maybe I am doing something wrong? How do I implement javascript into my project. Please help.

Make sure to check your file order so that the js files are loading in the correct order. That can many times keep something from working. To do this just right click over the word "Javascript" in the Design pane an that will give you a right click menu. Choose Include Order and arrange the files accordingly. The main bootstrap and jquery js files are locked as they always go first, but sometimes the rest can get out of order as you add new ones. See if that helps at all and let us know.
