5e Macro Proficiency

Quick question. How do I add proficiency bonus to macros? I used @{Proficiency} on the attribute macro designer in the character sheet, but it doesn't recognize it. Actually, I look on the attribute sheet, and I notice a lot of things I want are not appearing in the attribute list. Is it possible to figure out why they aren't in the attribute list, and how to get them there?

To help get you the expert assistance you require i'll move this to the character sheet forum, please could you let the community know which sheet it is you are using as i believe there are a number of 5e ones available. Thanks

If you're using the 5e sheet, it is @{PB}. I also suggest wrapping it in a nested roll to avoid the huge math when you mouseover it. [[ 1d20 + [[@{PB}]] + 0 [Misc Mods] ]]

If you're using the shaped sheet the PB attribute is already using nested inlines. All sections that are repeating (or psuedo-repeating) do not show up on the attribute list. For example anything spell related, new weapons, actions, etc on the shaped sheet.
