To get an unwavering weight value returned in a worksheet for a lighting device, I poll data from 'Functions-Specialized For Lighting Device-Weight' Instead of 'Records-Lighting Device-Weight'. This doesn't account for accessory weight, but will not return a 0 value on lighting devices that have accessories attached. I believe the weight field of lighting devices works in tandem with Braceworks, but unclear why the summary doesn't calculate correctly.
