If you see a blank page appearing as the introduction or end text, despite having deleted all text, it probably means that there is still some HTML code remaining on the pages. You can easily remove this when you are editing the survey, by clicking the HTML button in the HTML editor on the introduction and end text pages. Once here, you might see residual HTML code like break ( ) or space ( ). Simply delete any remaining text and/or code before clicking Save. Thereafter, the pages should no longer appear.
