Sounds like you are trying to manually do a sample selection 
correction. It is often easier to use -cmp- instead. Type in 
Stata: -findit cmp-. Being easier is of value in itself, but 
it also means that you are less likely to make a mistake. That
is a major advantage since the argument underlying these 
selection models is rather subtle, so it is very easy to make
a mistake when you try to do them manually.

Hope this helps,
Maarten
