Editing of form

Without thinking I edited the same form and lost data from people that had already registered before I edited the form. Any way to retrieve this data?

You will need to restore your form to a previous version to retrieve the data, you can do it with the revision history, here is how: https://www.jotform.com/help/294-How-to-view-form-revision-history
