Nick is right. After removing the parenthesis everything works fine. Also, variables created by lafconf and baseconf are dropped after running stgest and this prevented weibull from runing. Once I recreated them with makebase and makelag the weibull model and gesttowb ran also without problem.

Thanks!
Victor.
