Dear all,

```
I add a new country in a two-country cash-in-advance model which I successfully get the result. Yet I find "The rank conditions ISN'T verified!" after the modification. By mistakenly put another similar variable ostar(-1) rather than nspur(-1) in line 39, the condition was met. That does not make much sense to me. Can anyone help me figure out the reason why such error occurs? Please see the attached mod file. Many thanks!
```

There are 8 eigenvalue(s) larger than 1 in modulus

for 6 forward-looking variable(s)

The rank conditions ISN’T verified!
