I have replicated their code exactly but am getting the following errors:
*** WARNING in MODEL command In the MODEL command, the following variable is a y-variable on the BETWEEN level and an x-variable on the WITHIN level. This variable will be treated as a y-variable on both levels: COPE_T *** ERROR in MODEL command Observed variable on the right-hand side of a between-level ON statement must be a BETWEEN variable. Problem with: COPE_T
COPE_T is my mediator variable that I have not defined as a WITHIN or BETWEEN variable.
