hi,

I use the code of model in congdon's book--applied bayesian 
modeling(2003),example 9.5
by some modification for my AFT model as follows,and you can see what I do 
only is that I modify the line  # z[i] <- stain[i] ,I cancel it and in the 
line for data input, I use z instead of stain.

Though model's checking,data's loading,as well as data's initing said ok, 
when I began to update the model ,it said there were something wrong,I 
donnot know how to find what's wrong with my model by the Trap window,will 
you help me?

Thank you very much!!!

Jing
