[ADMB Users] Running glmm.admb

Hi,

I'm very new to R and gmml.admb so my apologies if my question is very
basic.  I'm looking at habitat preferences of seabirds on several
islands.  I have a number of fixed predictor variables as well as
island which, in my understanding, I need to include as a random
variable to account for pseudoreplication.  My response variable (CDP
- ie. the number of burrows of a petrel species per quadrat) is  
zero-inflated and overdispersed so I'm trying to use glmm.admb for  
count data with a negative binomial distribution. However, it requires  
a grouping variable which confuses me because surely that's also my  
random variable (ie. island)?

Also, when I write my command, I get the following error message:

Error: unexpected input in
"Model1<-glmm.admb(CDP~Slp+Evn+LP+VegCom,random=~Is,family=?"

Can anyone suggest what I need to do?

Thanks
