Dear Statalist Comunity;

I´m trying to run a synthetic control in stata 12.0 but I´m not getting because there are some missing values in the dependent variable.
My database has ten years and 28 states, there are just six missing data but even so the program doesn´t run.
I deleted these six rows but didn´t have success.
It will be possible to run synthetic control with these missing data? Somebody can help me?
Beforehand I´d like to thank you for the attention.
