What version of FS are you using? When I load that file in 5.3 qdec, it creates several discrete classes, see below doug

Hi Doug et al,
I'm trying to run an analysis in QDEC and continue to get an error that says that the QDEC GLM design creates 0 factors.
I'm attaching my data table here as well as the output of QDEC. I've tried deleting all variables in my data file other than one and testing just that comparison, but no luck.
Any thoughts are much appreciated.
Thanks, Kate
