Hello everyone,

this is the first time I post in this forum. I'm a new minitab user, I hope you can help me: I was doing a multiple way ANOVA with minitab "General Linear Model" tool. I have three factors, one of which (Peff) is random and a continuos variable. Minitab gives me the following error message:

GFMain 'n' 'Va' 'Peff';

Responses 'Fx';

FMeans C4000

*ERROR* No data in column.

What I did wrong?

If you need more details you'll just say.

(my english is not very good, so sorry).
