How edit dynamically data when the input field is biding with a collection list?

Thank you! I think this link maybe helpful as well, for someone who needs to do it with an image upload component.

File uploader element in collection

Yes, that I understand for a “normal” upload file, but when in a collection list, I just can’t add the input element. That’s why I suppose I need to create the variable, but I just don’t know how to use it in the workflow. [upload] The variables are visible when I add a upload file element NOT in a collection list. When adding in a collection list, the variables are not visible. [variable]

Thanks for the help!
