The Jacobian or the dynamic model contains Inf???

I get the following the error message when I run my code:
"The Jacobian or the dynamic model contains Inf. For more information, use options_.debug" Then when I use 'options_.debug" I get ans=0. I am not sure what's going on. Can anyone help?
I checked my equations for mistakes (many times) and I am pretty confident they are all correct. And the steady state is well defined.
