R help - Jan 2008 - Help with flexmix

Hello, 
 
I am using the package "flexmix", specifically the function
"stepFlexmix"
and was hoping for some assistance: 
 
Here is my input:
 
fit <-
stepFlexmix(trips~.,data=data.frame(traveldata),k=1:5,nrep=5,model=FLXMRglm(
family="gaussian"))
 
And I recieve the following error message: 
 
 *Error in FLXfit(model = model, concomitant = concomitant, control control,  :
1 Log-likelihood: NA
 
 
I'm not sure how to interpret this error. Any advice would be helpful. Thank
you.
