Thanks on the syntax.

I have to define Make , Model, Opening, where the users selection of Makes poplates the List for Models, and when you pick a Model I know the potential Openings. Take that further for other options if any else that is required for secondary filtering.

Others are Torque, %Hi, %Reverse, and the list goes on.

This is all used to determine what products we make to fit your needs for generating the proper power for your application. We make the device that pushes a fire trucks lader up or a cherry pickers basket into the air.

So I have a WinForm designed to help them get as few parts into a data grid or to print in a report.
