Cause
On a page in the project, no value has been entered for the property selected in the Number of pages / page name per property setting.
Solution
- In the Message management dialog, double click on the message to locate the relevant page in the tree view in the page navigator.
- Use the popup menu to open the Page properties dialog for the page and enter a value for the property specified in the message text, which you selected in the settings for the pages (command path: File > Settings > Projects > "Project name" > Management > Pages > Number of pages / Page name per property).
- Select the command Number of pages / page name per property. (To this purpose you first have to Customize the ribbon and then assign the desired command to a user-defined command group.)
The result is written to the Number of pages per property, Page names per property and Page counter per property page properties. - If required, start a new check run.
