Custom Integrator is not asking for parameters defined and attached to content set

I am creating a custom integrator to work with pricing.  The content set will download data from a specified price list.  I have created a content set and attached the parameter list name. But when I run

Create Document, it populates the content set name, but does not ask for the parameter field I defined.  I am attaching screenshot of my setup.

Also, how do you use the parameter in the sql query that the content set is based on?  I am currently using:  where name = $param$.price_list_name    Is this correct?  Is it case sensitive?

thanks
