"How to Filter Examples matching two attribute with the same value?"

Got 4 attributes in one table and need to filter examples when attribute A's value equal to attribute B's value.  I don't know which operator would work. I try to use the Filter Examples in attribute value, just don't know which regular expression would work( 'A = B' didn't work...it works as A's value = B)

 

Anybody know that?  Thx!

    Hi,

    Filter Examples with the option "expression" is what you want to use. The interface is like Generate Attributes.
