There might be a need to edit a form at different times after creating the form. This is usually done if you want to reuse a form, or request for more information from your respondents.
Edits made to a form can be major or minor. A minor edit gives rise to a minor version, which is a variation of your form created when you have made a small change to your form such as editing a field or saving your form. A minor version doesn’t cause any significant change on the form, therefore if responses are stored in Spreadsheet, a new sheet is not created. The versions of these kinds of edits are not usually stored.
On the other hand, a major edit will cause a major version, which is a variation of your form created when you have a made a significant change to your form such as adding or deleting a field, this type of change causes a new sheet to be created in your Spreadsheet if responses are being stored in the Spreadsheet and if responses are stored in Formplus, a new tab is opened to store responses for the newly created version. Responses of different versions of a major edit are stored for references, therefore no data is lost if you save your edits.
The different major versions of a form can be found in the Responses page of the form. Clicking on the date the version was created displays the responses for that particular version, as displayed in the image below.
