Ok awesome, the tabbed subforms are working a treat.
I went ahead and simplified the SOS tracking system. It was just far too complex for what was being done (in my very humble opinion). I deleted all of the related SOS tables and just stuck with the main SOSEvent table with fields for the events taking place and at what usage the SOS occurred.
I am getting to the PM part now on the details form and I am having a hard time figure out how I am going to implement this but before I ask any questions I am going to sit and let this run through my brain a bit and see if I can't figure out what I want....
