I used the snippet code from the website of Formidable fFroms to update the Woocommerce quantity input field with a form value. It worked well for a few months, but now it is not updating the Woocommerce quantity anymore.
In the attachment I also sent screenshot. The code i used is also in the snippet. I changed the field name to the right fieldkey. The Formidable Form support team couldn't help me because they said they tested the snippet code and it is working normaliy. But somehing at my site is trouble. I don't know what the problem is and how to fix it. I have no code skills.   I hope someone here can help me :)))
