I would have thought it would be easier to have just one query, with two calculated fields:
if([YourDate] between _add_months(current_date,-1) and current_date) then ([YourMeasure]) else (0)
if([YourDate] between _add_months(current_date,-6) and _add_days(_add_months(current_date,-1),-1) then ([YourMeasure]) else (0)
You might want to put a total around those...depends on what you're after. Obviously you also want the filter for 6 months in your query as well.
If there are any typoes in there blame it on a lack of coffee :)
