Optional Whisper of Ability

I have multiple characters that hold abilities, including many game rules (this is so I can make inline buttons on other abilities to look up said rule on the fly when needed). I want to add the ability to choose between whispering and posting to chat when using these abilities.  ?{Whisper?|No, |Yes, /w @{selected|character_name}} No works - it leaves a single blank and process the ability into general chat. Yes fails - it just adds the text and the processes the ability into general chat instead of a whisper.  I guess question is can it be done? if so what I am jacking up?  Thanks! 

Yes, this can be done, but the slash command has to be the first character(s) in the line, just remove the space after the comma: ?{Whisper?|No, |Yes,/w " @{selected|character_name} " } EDIT: Also, you should wrap the character_name in quotes to properly handle names with spaces (above is corrected to show this). EDIT 2: And of course, there can't be a space before the roll query

Thank you!

Happy rolling
