Percentage of Totals in Schedule

[hliS658H]

I need to calculate wall opening percentage in the schedule. I use filled region, one type for opening area, one type for the exterior wall.  How can I edit the schedule to make it look like below? The formula will be based on two totals, not sure how to do that.

Hi, 

there is no way to add a customized total directly in schedule as a row but there are other workarounds that could help. I would suggest you to have a look at the below thread. 

Please mark the solution if it helps.

Why can't you just include the Open Percentage Column and Total that Column? You can have both Total Exterior Wall and Open Percentage totals.
