I have assigned part numbers for each piece of DAX foam enclosed in each sub assembly part. I am trying to label them with balloons, with part numbers as the generated value instead of having to label each foam part. I added it in the Style manager, and it works for labeling the sub-assembly parts for example, backrest bottom, cushions armrests etc, but not the foam parts in each sub-assembly. As you can see in the picture below, the balloon part number value is empty. I have enabled my parts list in the B.O.M. thinking that might fix it, and still no luck. Can anyone help?
