Your pseudocode is not helpful because it does not show the exact code
that is resulting in the exact error you mention.  mlistLen is not
mentioned at all in your pseudocode, so it is impossible to say where or
what is going wrong.

Probably you forgot a global statement somewhere, but without seeing
actual code that causes the error it is not possible to give concrete,
helpful advice.
