@BabaJ, ok, thanks for your answer
@ObeidaZakzak ... ohh good to know, thanks a lot!

I mean, I want to access to the values of that parameters, not only the name of the attribute.
the field, the paramater could be empty or the user could enter an attribite name.

There's no need for backticks or double quotes.

string maskAttribute = chs("../attrMask");

Thanks, but I would like to access to the values of that attribute with a @`chs("../attrMask")`, and I get the same error message when it is empty.
