Thanks once again. It works.
However, I received a new error message as below.
Variable on the left-hand side of an ON statement in a | statement is a WITHIN variable. The intercept for this variable is not random. Variable: V1
I noted that you mentioned in another post that if V1 has random slop than it should be removed from the within list. However, if it is removed, how can we produce the random slope of the level 1 relationship related to V1?

I have just solved the problem I asked previously. I then received the below error message. However, I did not put any variable on level 3. Can you please help explain? Thanks.
The CENTER function with GROUPMEAN is not allowed for variables that exist on all 3 levels.
