Mobile form compatible with file uploads?

we have a contest running are getting feedback that they can not upload the file they get kicked out when that happens. Is this form mobile compatible can they upload the file via phones. 

Hi,

Our forms should be compatible with all devices and should be mobile ready.  I checked your page and it appears as though you have used the regular Javascript embed method.  This works in most cases but does leave the form open to conflict with the rest of the page.  This can occasionally cause issues with usage.

Try embedding your form using the iFrame embed method instead:

This should allow for your form to work the same as it does normally while embedded to your page.

If this still does not allow your users to upload files to your form, let us know and we will be happy to have another look.
