Why are you using stored variables? ---

The code looks good. I’m not sure why you’re getting NaN for your total. If you want to share the link to your project, I can take a look and see if there’s some other reason it’s not working right. If you stick with Thunkable, you may want to look into local databases and tables/spreadsheets. It can make your coding much more efficient. ---

Hey @adiyy.khanic22, try changing app var to stored var that sorted me out when I had those issues. ---

Hi @adiyy.khanic22, when you use a “stored” variable it is “undefined” at the beginning. And when you add a value to it, it keeps being undefined. So just enter a block to set it to a starting value like this: ![grafik](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/c/cccc59d2102999ee8de09fafcf910c31a09befc7.png) - Be shure to use the Block “Screen1.Starts”, and **not** “Screen1.Opens” - if you change the type of score from “stored” to “app” then things are easier, but the value will get lost after closing the app. A “stored” variable will be present the next time you start the app. ---
