Problems in 050002_CreditScoring

Hello everyone: 

I'm trying to replicate a metanodo found in 050002_CreditScoring. It is a metanodo string where all variables are taken and converted into such number of use in a neural network or SVM. The metanodo in question is called Nominal numeric and specifically to the problem apparently have in shaping the column node as filter to run, does not show me any column. In configuration I put "0" parameter is controlled by a variable, as outlined in 050002_CreditScoring. Can anyone give me a help? 
thank you very much
