When I open the SETUP in datafile, some variables appear in red (see attachment) ¿what does it mean?
Curiously If I try to create groups in a datafile with red variables the procedure crash (but works fine in data files whit all "white variables")
PS. the datafile came from saving POS results

Red variables indicate a setup problem.

Please open the Setup dialog via "Setup" from the toolbar and correct all issues. A typical issue is that there are multiple columns in your datafile that have the same label in their first row.
