I am having a different issue with CHAID.

It is supposed to be able to take numerical attributes, however when passed numerical attributes it says  "Numerical attributes not supported."

Hi all,
booth issues should be fixed in the current version. So I would suggest dating up as soon as possible. The wrong meta data propagation will be available with version 005.
