How to create a scorable survey

Questions about Thunkable

I’ve assigned scores to various answers throughout the app. This is a survey, so when a user clicks on a button matching a condition they wish to report, the app turns that button red and changes the variable “by 100”. I have set the initial variable number to “0.” The variable is a button. I do not know how to grab whatever value is in the button so that I can increase it by the value of the user-reported condition. I thought I didn’t have to do that with a “when, do” logic statement that commands “change [app variable score] by [100]”.
