Space Required Variable?

Greetings,

I have been searching for days in an attempt to figure this out. I am using addsize for each section and the components page is calculating the total required size correctly.Is there a variable that (required size) addsize selections are being store in?

If not, it possible to capture the total size of selected components and pop this number for further use?

Figured one way to do this using SectionGetFlags and IntOp during .onSelChange.
