Dear Drs Muthen,

I am working on a multi-level SEM. Both independent and dependent variables are latent construct.

In the model,

Latent_A (individual) and Latent_B (group) will affect Latent_C (individual)

I include the BY statement for Latent_C at the WITHIN level, and at the BETWEEN level, the variable cannot be seen. See the code below.

MODEL: %WITHIN%
LA BY LA1 LA2 LA3;
LC BY LC1 LC2 LC3;

LC ON LA;

%BETWEEN%
LB BY LB1 LB2 LB3;

LC ON LB; <====

There is an error message saying that "LC is unknown". Probably because I create it at the WITHIN level.

Please advise what I should do.

Thanks a lot.

You need to define LC on both levels using different names for the factor, for example, LCW and LCB. The factor loadings can be held equal across levels if this fits the data.
