Despite a number of forum answers, I still can’t figure out how to increment a numeric variable. The following flow works for toggling the Y/No variable, but it keeps changing the count-up variable to null. Can I do this with the built-in cards, or do I need another app? I was also hoping to avoid having to use a Script. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/3/c37946e2167b95f1c21b726e7a58a96430ffc815.png) ---

Make sure you select the variable ‘count-up’ in your formula. It now looks plain text ![IMG_1969](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/d/bdcba12305cd3b95333f1b594a48b9ae8a41ed32.jpeg) ---
