Pulling the 'name' from a name/value pair

Hi All,

First time poster so hopefully I do this right.

Twine 2.0.11, Sugarcube 2.8.0

I've created an array and successfully sorted it like so:

<<silently>>
<<set _statroll = [["will",random(1,20) +$player.will],
["str", random(1,20) +$player.str],
["dex", random(1,20) +$player.dex],
["con",random(1,20) +$player.con],
["wis",random(1,20) +$player.wis],
["int",random(1,20) +$player.int],
["chr",random(1,20) +$player.chr]
]>><</silently>>

before:<<print _statroll >>

<<print _statroll.sort(function(a,b){return a[1] - b[1];})>>
<<print _statroll [6]>>

My goal is to determine the maximum roll each time this passage is visited and provide different options based on what that maximum was.

My issue is that when I print the _statroll[6] I'll get something like "will, 13" when all I really want to see is "will".

Is there a way to do that?

Any help is appreciated.

Thanks!
