$SUM_PARTS and $COUNT_PARTS Example in the Sand Box

Hi everyone,

I have been roaming the SandBox in the last few days as I was prototyping a way to count up doors for a project I am on.  I have reached a solution for that based on some forum postings that the knowledgable Steve Schneider had contributed on using a "count" characteristic.  However I will save that for another day, as it is nearly midnight and I have to give a demo in the morning.
