Could you plz help me guys.

I am working on something like this subject and every-time I operate this code, it gives me "Undefined function or variable 'x_ga_opt'". So if anyone has the code, could you plz email it to me.

Can you examine the code to see if it looks like a function or a variable? Maybe it is a variable that was supposed to be defined upstream in the code but didn't for some reason. Or maybe there is a script m-file out there that is supposed to define this variable. Etc etc. You really haven't given us much to go on. Can you search all of the m-files for the string 'x_ga_opt'?
