Is there a particular reason why you're using running totals instead of summaries?
Try this:
1. Group by Title.
2.. Group by Option.
3. Create a summary at the Option level that will count/sum whatever you need.
4. Create a summary at the Title level that will count/sum whatever you need.
If you need to continue to use the running totals, you'll need to create a second one to do the running total by option - have it reset on change of the option group.
