You can have one listbox for the three fields. Selecting one entry can be made to select three fields using event triggers.
So if you select line '1,Name1,5', it is equivalent to selecting '1' in the listbox for StepNumber, 'Name1' in the listbox for StepName and '3' in the listbox for 'Qty'.
From this you can have gauges with conditional calculations.
A sample qvw file is attached for your reference.
Hope this helps.
