I added these two codes for a text box and upload files. They were added, but when I add a product to the cart I get this error message: Parameter Missing or Invalid: Required parameter missing or invalid: items.
What do I need to add to the code or take away, for it to work?
Special Requests-Please add here
{% form ‘product’, product, class:form_classes, novalidate: ‘novalidate’, data-product-form: ‘’ %}
Upload file here
{% comment %}
Custom form field to add a line_item.properties entry with the name “upload”, containing the link to the uploaded file.

Upload
{% endform %}
