The byline says No permission to add variables to this page
What you are seeing
In Insert variable, the insert button is unavailable with No permission to add variables to this page. Or, after inserting, a message says The variable could not be added to this page.
#Why it happens
No permission to add variables to this page: you cannot edit the page. Adding a variable changes the page, so it needs edit permission.
The variable could not be added to this page: the change could not be saved, for example because permissions changed or the page could not be updated at that moment.
#What to do
Ask for edit permission on the page, or ask someone who can edit it to add the variable. If you can edit and the insert still fails, reload the page and try again, or add the variable from the editor instead.
