i added a code where when you click on a image the cookie variable number go down, but when I go to live test nothing works. here is my code link and image
What value is your app variable Cookies initialized to? Is it initialized using a math block or a text block? Maybe show that part of the blocks in a screenshot, too.
Try adding a vibrate block to certain parts of your code and test it in Thunkable Live to see if it reacts to your click (above the If block and then if that works, within the If block).
Also, which screen is this on? It’s confusing when you post a link to a project with many screens and then expect us to know which one to look at.
Edit: I see the Shop screen event block. Still good to include that info in your post, though.
