Roll Query and Grouping Keep

I know you can build a grouping keep roll. For example, this /r {d6,d12}kh1 would roll a d6 and a d12, keeping only the highest one. However, I want to include this within a button on a custom character sheet. Additionally, I want to give two different grouping options for the player to choose from I would like the players o be prompted to choose between grouping option blue of {d6,d12}kh1 or grouping option red of {d4,d8}kh1.  I realize this format ?{Pick|Blue,{d6,d12}kh1|red,{d4,d8}kh1} is wrong. The {} within the groupings cause it to break. Can someone advise how to make it work?

You'll need to substitute for the right brace in the query, otherwise the query will evaluate the first closing brace as the end of query. example of an inline roll; [[ ?{Pick | Blue , { d 6 ,d 12 } kh1 | Red , { d 4 ,d 8 } }kh1} ]] button example; <button type="roll" name="roll_foo" value=" [[ ?{Pick | Blue , { d 6 ,d 12 } kh1 | Red , { d 4 ,d 8 } }kh1} ]] "></button>

Thanks, but that does not seem to work. I copied the button example you posted. But when the query comes up it asks me to choose  Blue,{d6,d12 as the input value.

Interesting...  Seems like another weird behavior of how the vtt parses sheet code.  Try double substituting.  Replace "&" with & like so; <button type="roll" name="roll_foo" value="[[ ?{Pick|Blue,{d6,d12}kh1|Red,{d4,d8}}kh1} ]]"></button>

The commas also need substituting. You can also move everything except the commas outside the query: { ?{Pick|Blue,d6,d12|red,d4,d8} }kh1 And you don't need to use commas. In this kind of operation, a + works fine { ?{Pick|Blue,d6+d12|red,d4+d8} }kh1 It'll still select the single highest die.

Perfect! This worked. Thank you both so much for the replies.
