If you offer trial versions of your workbook, they can display a nag screen to remind the end user that they must purchase the full version. The nag screen can optionally show a “Purchase Online” button that will open the user's web browser to the URL of your choice. The goal is to redirect end users to your store or purchase web page.


As in the previous topic, it is possible to use the %SYSTID% text in the URL to insert the System ID.
