I created a number variable, which I would like to use with a Radio Group component. I would like the radio answers to add 1 or 0 to my number variable. Unfortunately, the only variable I can select from the Variable drop-down is a string variable. Any ideas as to why I am unable to use my number variable? ![number-variable](https://canada1.discourse-cdn.com/flex031/uploads/evolveauthoring/original/1X/ee7fd41d23874ef04ef58734a4faa210dbccd8ce.jpeg) ![component](https://canada1.discourse-cdn.com/flex031/uploads/evolveauthoring/original/1X/2bd9a8118353ab1a1ff1422b694cf71f759edbb4.png) I am attempting to create a self-assessment that, once completed, presents the learner with a final score and offers feedback based on that score. If anyone has built something similar, please let me know which components you used. Thank you for any suggestions. ---

Hi, I’ve built something similar to what you describe using the slider input component. The user slides on scale rating like the below and submits: 1 = very false for me 2 = somewhat false for me 3 = somewhat true for me 4 = very true for me That then writes the number to a number variable which then totals up to provide feedback using a bunch of logic. The bottom line is only certain variable components can write to number, boolean, or string, and radio will not write a number. Take a look toward the bottom of topic 1 in this course: [https://juvolearningsolutions.evolveauthoring.com/courses/5ef45fb220dcc2481c48a361/preview/index.html?isShared=true](https://juvolearningsolutions.evolveauthoring.com/courses/5ef45fb220dcc2481c48a361/preview/index.html?isShared=true)
