Users not able to submit form

Hi,

I've been having for quite a while this problem with chronoforms. I set up a multi-page form. About 15% percent of the submissions were incomplete (showing only the data from the last or last & second to last form pages). I implemented JS validation and serverside validation, I am checking if the user is not getting to the 2nd, 3rd, etc pages via direct link (as suggested here), I am even blocking the access to the form for the users that have no cookies enabled (checking with JS). Whenever I test the form everything works perfect; but there are still users that cannot submit the form on the last page because the form is not remembering all the required data they filled in in the previous pages. It doesn't seem to be browser-version-related or device-related.

Does anyone have an idea what might have happened? Please! It's starting to drive me crazy.
Many thanks.

Hello doulfe,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
How can I ask new users for information and not ask logged in users?
How to post information from a Chronoform to ZoHo
What are the 'Easy Form' and 'Form' Wizards?
How can I add a mask to format a form input?
My form doesn't submit - send emails - save records
I get a blank page when my form submits?
How do I show a 'loading' image when the form submits in CFv5?
How do I show a 'loading' message when the form submits?
P.S: I'm just an automated service😉

Hi doulfe,

Nothing obvious comes to mind. I assume that you are using the Multi-Page action to pass the data between pages?

I'd suggest that you set the form up to save the submitted data after each page submission and update the same record after each page. That should prevent any data loss and give you more reliable results.
