Hi I have an experiment with one between subjects factor (Lets say FactorA) with two levels: Big and Small and one within subjects factor (FactorB - Quality) with three levels: 1, 2 and 3 - corresponding to High, Medium and Low.
I want to examine the effect of both the factors on the Dependent Variable measured after each of the participant was put into one of the two conditions (Big or small) and evaluate some things (High, medium and low) : Dep_Var1, Dep_Var2 and Dep_Var3.
I am using the following code:
proc glm data = Dataset.data;
class FactorA FactorB SubjectID;
model Dep_Var1, Dep_Var2 Dep_Var3= FactorA|FactorB /ss3;
repeated SubjectID, FactorB;
lsmeans Condition/pdiff stderr;
run;
However I keep on getting the following statement in the Log:
NOTE: The CLASS variable FactorB has only one level: '1'.
ERROR: Ambiguous level information in REPEATED statement
Here's a snippet of the data for easy reference:

I realize that I am making a mistake in how I have input FactorB, but cannot figure out what to do here. Any help is appreciated.
Thanks.
