Hi everyone

I'm new to Mplus and I'm finding very difficult to get going with it! I'm trying to run a two level moderation model, however I get several error messages as following:

THE MODEL ESTIMATION DID NOT TERMINATE NORMALLY DUE TO A NON-ZERO DERIVATIVE OF THE OBSERVED-DATA LOGLIKELIHOOD.

THE MCONVERGENCE CRITERION OF THE EM ALGORITHM IS NOT FULFILLED. CHECK YOUR STARTING VALUES OR INCREASE THE NUMBER OF MITERATIONS. ESTIMATES CANNOT BE TRUSTED. THE LOGLIKELIHOOD DERIVATIVE FOR PARAMETER 23 IS -0.84146672D+00.

Can you help me with my mplus code?

VARIABLE:
NAMES ARE clus W X M Y;
USEVARIABLES ARE clus W X M Y;

CLUSTER = clus;

WITHIN = X;

BETWEEN = W;

ANALYSIS:
TYPE = TWOLEVEL RANDOM;
ALGORITHM = INTEGRATION;
ITERATIONS = 1000;
CONVERGENCE = 0.00005;
ESTIMATOR = MLR;

MODEL:
%WITHIN%

T | Y on M;
M on X(A);
Y on X;

%BETWEEN%

T on W(B1);
[T](B0);
Y on W;
W with T;

MODEL CONSTRAINT:
NEW (ind_h ind_l);
ind_h = (B0 + B1*(.67))*A;
ind_l = (B0 + B1*(-.67))*A;
NEW (diff);
Diff = ind_h - ind_l;
OUTPUT: SAMPSTAT CINTERVAL;
