Laura,
There are syntax errors in what you say you ran.
xtivreg2 lnct3 $rhs (q12c q21c q16c q17c=3D$QIs_prev $iv1), fe cluster(cpa)= orthog($QIs_prev $iv1) endogtest(q12c q21c q16c q17c) small ffirst
has an "=" after the cluster option, and "3D$QIs_prev" will give you an illegal variable name, I think. So this is probably not exactly what you did.
In any case, can you (as per the Statalist FAQ) tell us basic things like which version of Stata you are using, which version of xtivreg2, etc?
