Summing strings of rolls?

Hey guys, newer to the whole macro thing here (so hopefully this is a simple script that i'm missing), but i'm trying to throw something together like the below:  /e uses ability! d4 damage [[ ?{d4?|Yes, 1d4|No, 0} ]] d6 damage [[ ?{d6?|Yes, 1d6|No, 0} ]]  d8 damage [[ ?{d8?|Yes, 1d8|No, 0} ]] d10 damage [[ ?{d10?|Yes, 1d10|No, 0} ]]  d12 damage [[ ?{d12?|Yes, 1d12|No, 0} ]]  d20 damage [[ ?{d20?|Yes, 1d20|No, 0} ]] What i'm missing, however, is a sum of those 6 individual rolls total then halved.  ie: something like:  [[(a+b+c+d+e+f)/2]] Hopefully this is a simpler task but i'm stumped!   Any help is appreciated! 

In roll20, you cant use rolls in two different ways. So if you want to show the individual rolls, you cant sum them up. If you want to sum them up, you cant show the individual rolls.

The closest you could get is using the non-inline roll syntax with roll tags: /r ?{d4|Yes, 1d4 [d4 damage]|No,0}+ ?{d6|Yes, 1d6 [d6 damage]|No,0}+ ?{d8|Yes, 1d8 [d8 damage]|No,0}+ ?{d10|Yes, 1d10 [d10 damage]|No,0}+ ?{d12|Yes, 1d12 [d12 damage]|No,0}+ ?{d20|Yes, 1d20 [d20 damage]|No,0}

Darn!  Thanks for the response gents.
