[Resolved] Additional group Sum question

[BIGGY]

I noticed a post which asks about summing and was resolved by simply doing a 'Summary' from the Crystal menu. I have the same problem, but I need one value (which must be in the report) removed from the summary.

For example there's a field:
{Intran.Quantity} which I need summed on a group level, however I need it filtered by the 'Type' field: {Intran.Type}. The report SQL pulls in several 'Type' (IN, CM, RC). I need just the IN and CM types summed on a group level. Just running a summary does give me the correct groupings, but the results are high because the RC's are also included.
