Hi Keith. There are no AICC variables listed under the reserved variables either. I don’t have a separate tab for the variables, so I’m probably using an older version of Lectora (2007) than you are. As far as I know, I don’t have a “variables used” window. In any case, as soon as I switched content type, all AICC variables disappeared.I’m not including a title manager frame (at least, that box is unchecked when I publish). Thanks for the suggestions. I’ll keep trying.
