This run-time message only occurs while previewing a script, and informs you that the currently selected page of the script contains tokens that are replaced by xtags (usually this comes from the text resulting actions of macro tokens).

This message does not indicate that there is any error with your token or with the Xtags text that is replacing it; it just informs you that Xtags cannot be previewed.
