AMOS error message

Nabaneeta Saha
Hello,

I am trying to run a path analysis with AMOS, but getting an error that says

"Either the constraints on the parameters are or the initial parameter
values are bad. This error can occur, if you request a maximum likelihood
solution while specifying initial parameter values that present the
population covariance matrix from being positive definite.
Check to make sure if each endogenous variable has a error variable"

Could anyone please help me with this? where should I request the initial
parameter values?

My dataset is field collected data, of a forest ground community and I am
trying to establish the relationship between prey and predator population.
My dataset has quite a few zeros in it.

Thanks
