Multiple Keep / Drop Dice with Target Number / Successes

I wanted to do {10d20+3}<14 with advantage so I tried {{10}2d20kh1+3}<14 and {10{2d20kh1}+3}<14 in vain. Any idea how to do so? Thank you kindly for your help

I'm unclear o the roll here. Are you saying you want to to do 10d20, twice, and keep the group of 10 dice that rolls highest? Or you rolling 2d10, keeping the highest, and then repeating that 10 times and adding them all together? The <14 there is confusing me, also. What purpose does that serve, especially when you also have a +3 bonus. Can you describe in plain English, without using roll20 math, how this roll should work?

The OP 1st code is 10 DC15 saves (w/ a +3 mod), finding out how many failures. Then in the OP I attempt to convey what I want to do the same thing but with advantage (ie: from Danger Sense or Gnome Cunning) including my attempts at it.

I dont know the rules of the game you're playing (some from of D&D I guess), so you'll need to explain what the roll is and what "with advantage" means in this case.

GiGs said: what "with advantage" means in this case. ie: 2d20kh1 and to find out about the rule: dnd 5e - What is advantage? - Role-playing Games Stack Exchange .

You havent answered the questions in the first two lines of of my first post here.

I was editing. Also you may want to know about dnd 5e - Do you have to beat or equal a DC? - Role-playing Games Stack Exchange .

Looking back at your first post, it looks like you need to roll 2d10 ten times (but seem somehow unable to say this directly). Unfortunately the only way to do this without the API (a Pro feature) is manually. Going by your original roll, one way would be like so: [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]] + [[{2d20kh1+3}<14]]
