![t|534x500](upload://aEaYAXJeKQw1LIB0YS9xfua5Z0 Sorry can someone tell me why I only see the error message? I generated a qr code with the word “ciao” but when it scans it always gives me an error message. Where is the error in the blocks in this image? Thank you

Debug tip of the day #1

Try printing each step to a label if possible

In this case, print the value block to a label. Make sure the value is what you’d expect it to be.
