Issues with testing a single file upload form

I embedded the source code on a code block for the file upload form I made through jotform. A file is the only thing that people need to upload on the site before they hit submit. When I test this out, it doesn't work and tells me that all form fields are required to be filled out before submitting- but there are no other required form fields (besides hitting the submit button). This site is being done through squarespace. I made the form and tested it out before I actually signed up for an account through jotform (the free one)- would that have been affecting it? I have yet to test it again since I signed up for a jotform account today.

It will help us find out more about the cause of issue if you can share to us the URL of your website where you have embedded the form using its source code.

Just in case you are not aware also, using the form's full source code embed, requires re-embedding the fresh source code every time the form is edited/modified in the Form Builder.

So, one possible cause of issue on your form not working properly on the website, is that it could be not the updated version of the form. 

You can do a test of the form using its direct URL first, and check for problem. When all is according to what is needed, you can get the source code again and re-embed the form to the website.

Hope this help. Let us know if you need further assistance.

Thanks.
