Hi analistaactivosdigitales,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. I'm sorry that this is happening. We had a temporary issue yesterday with the File upload field but our Developer Team has already solved the issue so it should all be working fine now. When I tested your form, everything worked the way it was supposed to. Take a look at the screenshot below to see my results:

I've cleared your form caches. Can you give it another try and let us know what happens? If you're still having the same issue, can you confirm if this happening to your other forms? Have you tried uploading a file in your form using a different device? Can you share the device details and browser that you're using?

Keep us updated and let us know if you need any more help.
