Macro of Average for two Attributes

Hi guys pretty new at this. Just starting writing own macros. One I can not figure out for our game is I want get the average roll of a characters highest and lowest attribute. I realize I will probably have to copy paste the specific high and low attributes of each character but looking for a general formula.  Any help is appreciated.

Something like this: [[(@{selected|Charisma} + @{selected|Wisdom})/2]] You can replace "selected" with a character's name. If you put this roll on a character sheet (say, in an ability), you can omit the "selected" or character name, entirely. This does require you to determine the highest/lowest. With the API (if you're playing in a game started by a Pro subscriber), MathOps could handle getting the highest and lowest attribute dynamically (with a max() and min() function): {& math (max(@{selected|Strength},@{selected|Dexterity},@{selected|Consitution},@{selected|Intelligence},@{selected|Wisdom},@{selected|Charisma}) + min(@{selected|Strength},@{selected|Dexterity},@{selected|Consitution},@{selected|Intelligence},@{selected|Wisdom},@{selected|Charisma}))/2}

Do you mean something like this? [[ ( @{selected|attr1} + @{selected|attr2} ) / 2 ]]

And if you want to show only whole numbers, you can use floor(round down), ceil(round up), or round(round to the nearest), like so [[ round( (@{selected|attr1} + @{selected|attr2}) / 2) ]] o, if you don't want to use inline roll brackets /roll round( (@{selected|attr1} + @{selected|attr2}) / 2)

Thanks Guys! You all are the best. Got it working perfectly. Think I was adding random "roll 20" that weren't required.
