The 'Row Group Summary Line Descriptor' is part of the value of the field, not the name of the field itself. So in your case, coming out of your Summary output, would be one feature with an Attribute field of id, with a value of id Def_points_Sum. The way you have your connections now, you have a separate feature for each of the unique 'id's' in your data. To get the result you are looking for, I believe you would need to make the connection to the Summary port of the AttributePivoter, and use the value from the 'Def_points' field in your InlineQuerier.
Have you used Inspectors before? Right-click on the output port of the AttributePivoter, and click Connect Inspector. This will allow you to visualize what is coming out of each port, and subsequently into the InlineQuerier
