Hi There,
I am attempting to run a two-level 2-1-1 mediation model where the mediator(extfam) and outcome (tcn_vop) are dichotomous, the level-2 IV (cimmicon) is continuous.

I have been using page 25 the below presentation as a guide:

Names are
cnty tcn_vop extfam cimmcon ;
cnty tcn_vop extfam cimmcon;
cluster is cnty;
between is cimmcon;
categorical is tcn_vop extfam;
TYPE= twolevel random;
s_b|tcn_vop on extfam;
[s_b] (bw);
extfam on cimmcon (a);
tcn_vop on extfam (bb);
tcn_vop on cimmcon (cp);
s_b with extfam tcn_vop;
new (direct indirect);
indirect= a*(bw+bb);
direct= cp;

After running the code above, I get the following error. But it seems that I have specified the between and within components as denoted in Hayes' example. Only cimmcon is at level-2 as with the example. Any advice would be greatly appreciated.

*** ERROR in MODEL command
Observed variable on the right-hand side of a between-level ON statement
must be a BETWEEN variable. Problem with: EXTFAM

You use the extfam variable as a predictor on both within and between by which I think you mean that you want to consider a latent variable decomposition of extfam into a within and a between component. That decomposition, however, is not available when a random slope is defined for the variable (see UG ex 9.2). You can create a cluster-level counterpart by using the Cluster_Mean option.
