Hello everyone,
He tried many times to solve this problem but I do not get it, I also reviewed the forum many times but I also do not find a solution.
I need to make a multi-page form that has a file upload field on the first page, that this field is mandatory and that only pdf files can be uploaded. My idea is that the first page validates if it is a pdf file and if it is not, that you can not go to the second page of the form, is this possible?
Thanks in advance.
regards
