problems with the lmest function in R

Question

When fitting the model for latent transition using R's LMest package, I had problems inserting covariates into the fit. My response variables are binary and my adjustment variables are binary. My database is in long format as the prints will show. I tried a few ways but they all return the same error message. I will post prints that show. Important note: The base is balanced. I'm waiting for answers that help me.
