what is in $states?
Looks like $states[$state] is not an array.

And don't use & reference operator in foreach loop, there can be strange
side effects if you don't act carefully with it.

However, I tested that myself by entering text, or by entering just 2 digits, but there was no error.  FYI, I do have code in the script that catches faulty input and warns people in their browser to go back and re-enter the correct data, so I'm at a loss as to why this is happening.
