Hey, I’m trying to use the createRadio() function, but I get this error: ```auto Uncaught ReferenceError: createRadio is not defined at setup (p5js-temp-sketch_220402a1584838079584472986.js:4:3) at m. (p5.min.js:3:230028) at m. (p5.min.js:3:229048) at new m (p5.min.js:3:232427) at n (p5.min.js:3:226962) ``` my code: ```auto let radio; function setup() { radio = createRadio(); radio.option('black'); radio.option('white'); radio.option('gray'); radio.style('width', '60px'); textAlign(CENTER); fill(255, 0, 0); } function draw() { let val = radio.value(); background(val); text(val, width / 2, height / 2); } ``` HTML file: ```auto ``` Do you have any idea? Thanks 🙃 ---

That’s strange. Your code runs perfectly on my browser, which is Chrome on a MacBook Air. ![radio](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/7/f/7f0f896f5552d5bb4fbdc3328b2ac9a856162189.jpeg) _EDIT (April 2, 2022):_ I did change the name of the sketch file, but that shouldn’t make a difference. ---

Yes that’s strange, if I use the P5 web editor it’s working, but if i use the Processing 4 IDE (in the p5.js mode) it raise that error ---

Perhaps you have a corrupt local copy of the `p5.min.js` file installed. If so, a fresh download of it could address the problem. ---
