Brian, Thank you very much for your prompt response. I've corrected
this silly mistake of mine, but I'm getting another one now.

Where does the restriction come from?
Actually, I using your code (Brain Poi, 2008) to estimate a seven
group demand system and I want to apply/test a test developed by
Browning and Chiappori (1998). Therefore, I want to test the following
restrictions (see in the following program routine I am sendig

    scalar `g81' = `g13'*`g24' - `g13'*`g42' - `g31'*`g24' + `g31'*`g42'
    scalar `g82' = `g14'*`g23' - `g14'*`g32' - `g41'*`g23' + `g41'*`g32'
    scalar `g83' = `g12' - `g21'
    scalar `g34' = `g43' + `g81'/`g83' - `g82'/`g83' so on.

The problem is that I'm getting r(480) indicanting that I have missing
values or wrong initial values.
Can you guess how can I correct this mistake?


I don't see anything obviously wrong with your program, but if you send me (not the entire list) your dataset, I'd be happy to play with it and see what is wrong. I'll report back to the list once we find the problem.
