Can.t set AICC_Lesson_Status

The publish for SCORM option is telling me that I have to either have a scored test (I have a test which is graded, that's different?) or set either AICC_Lesson_Status or AICC_Score.I tried to do that, but I can't figure out how. If I create a Modify Variable action neither of those variables are available in the drop down list. But if I create a new variable with that name I get an error that says "The variable name you have chosen is already included in the current title (or reserved)."I am using a demo version of Lectora. Is this a limitation of the demo version, or am I doing something wrong?Thanks.- Tom
