2/3 rds of a digitized book has to do with regular production options (RPO's) available for upgrade as opposed to default base equipment or equipment standard to all produced.  Having watched the 'big button' video series last night, that looks like the best way to approach which parts are supposed to be on the car based on the option selected, but for the programming involved and complexity of this particular project.

Wondering, since I've already been playing around with radio buttons, even if less elegant, could they denote which parts to include/exclude from the recordset and if so, how to get them to function based on their true/false properties?
