Buttons are used to move from one page to another in the script.
Field Name
Give your field an appropriate name. This is particularly important if using it in a calculation or report. Changing a field name will not automatically update corresponding reports that use that field.
If you have applied any validation to any of the fields on your page, you will need to check the Validate Page option on a button that links to the next page. This will check all validation settings against all fields on the current page and pop an alert box if conditions are not met.
