Sorry again for the delay in replying, I've better data for the next week so I should be around on the forum more now.
The total on the right is for work done on that component. It doesn't include the original item cost. (RVCLB has always worked this way.) If you create a record in the Service screen for that component, that's when those fields will be populated. If this is what you're doing but it's not working, please let me know, as it works fine here. Thanks!
