A page break splits a BOS survey page into two pages. Page breaks can only be inserted between two existing items on a page (e.g. between two questions or between a note and a question).
A page break cannot be removed. If you have added a page break to your survey that you wish to remove, the only way to resolve the situation is to move all of the items from the unwanted additional page onto another page, and then delete the unwanted extra page.
Page breaks can be inserted into launched surveys and provide a way of splitting your survey into smaller pages without having to copy and re-launch the survey. However, items cannot be moved and pages/page breaks cannot be deleted once a survey has been launched, so please take care inserting page breaks into launched surveys. The action cannot be undone.
