Hi Gang,

I switched over to 3dMVM, like you suggested. Now I'm getting an error I can't seem to solve. I've seen this elsewhere on the message board, but the solutions don't seem to apply.

Again, I have two within-subjects variables of interest, one continuous between-subjects variable of interest (Anx), and four covariates of non-interest (two of which are continuous). I'd like to model the three-way interaction between the two within-subjects variables and Anx.

When I run the code below, I get this error: Incorrect level coding in variable Anx : :

Any recommendations for fixes? Should I instead list "Anx" as a qVar, then model the interactions of interest in glts?
