Right, that has to do with the Python interpreter, which is where you are 
inside expr="...". Python variable names must start with a letter. However, 
you can get around this by using getitem as in:

<dtml-in expr="_.getitem('2001').objectValues(['Folder'])">

This also works good if the id contains spaces, periods, dashes or any other 
character that is not legal in a Python variable name.

happy Zoping!
