Generalized linear models error

Giuseppina Chiri
Dear list,
I wonder if anyone could help me with this error message I get when
running GENLIN.
I am trying to build a multi-level model with individuals nested into 6
states. The outcome variable is binary and all the predictors are either
binary or categorical. The ID (newidcode) variable uniquely identifies
individuals in the sample.
Below is the syntax I used and beneath that is the error message I get.
I am new to this and perhaps I am doing something wrong, so any suggestion
is welcome.
Thank you
Giusi

 Warnings
There is at least one invalid case in the last iteration. A case is
invalid if there are errors in computing the inverse identity link
function, the log-likelihood, the gradient, or the Hessian matrix in the
iterative process. Only the iteration history is displayed.
