QR code generation - Zoho CREATOR

QR code generation - Zoho CREATOR

I have been searching for a while now - cannot find solution for a simple problem.

I need to generate a QR Code based on the input in a form field:
Say, on user input in the "Code" field is AIRW-7777 (string), a QR should be generated as an image in the field "QR" (image) that I can store and print out for labeling purposes.

I have found a few topics where it is recommended to use the this script in Workflow based on User Input (in the "Code" field):
URL = "<img src='https://www.barcodesinc.com/generator/image.php?code=" + input.Code + "&style=197&type=C128B&width=271&height=50&xres=1&font=3'/>";
input.QR = URL;

The result - in my "QR" field I can see exactly this "https://www.barcodesinc.com/generator/image.php?code=AIRW-7777777&style=197&type=C128B&width=271&height=50&xres=1&font=3", but not an image of QR code.

What am I doing wrong, please?
Thank you!
