I've made a simple Javascript code for a shopping basket but now I have realised that I have made a error with making it and don't know how to fix it. What I have is Javascript file but I have also included the images source and the addtocart button as well, but What I am trying to do now is make 2 files one a .HTML file and another .JS file, but I can't get it to because when I make a button in the HTML file to call the function from the .JS file it won't work at all.
