Help Needed - Azure ML - Text Prediction

Hello! I just started to learn about Azure ML and I'm trying to do a machine learning model with text prediction for environmental samples, using for example, the hypothetical training dataset:

Variable	Class
Sandy Clay	Clay
Sandy Clay, yellow	Clay
Sandy Cla, yelow	Clay
Clayed Silt, fine	Clay
Silty Sand, with concrete	Sand
Sand	Sand

 

I did a very simple model in Orange (3.8), as shown below, however I'm experiencing some difficulties to do the same model in Azure ML:

Some Azure ML expert could help me?

 

Thanks in advance!
