Hi I hava a problem in running my openbugs model my model is:

model
{
for(i in 1:N)
{
y[i] ~ dpois(mu[i])
log(mu[i]) <- alpha + beta1*x1[i] + beta2*x2[i] +beta3*x3[i] + u[i] + v[i]
u[i] ~ dnorm(0, precu)
}
v[1:N] ~ car.normal(adj[], weights[], num[], precv)
for (k in 1:sumNumNeigh){ weights[k] <- 1}
alpha ~ dflat()
beta1 ~ dnorm(0,1.0E-5)
beta2 ~ dnorm(0,1.0E-5)
beta3 ~ dnorm(0,1.0E-5)
precu ~ dgamma(0.001, 0.001)
precv ~ dgamma(0.1, 0.1)
sigmau<-1/precu
sigmav<-1/precv
}

when I want to run it in openbugs It get error Please help me to fix it
