Unsure why this macro doesn't work? (includes API scripting command)

I'm trying to create a drop-down macro that lets me toggle between different light states for tokens. This is my macro: ?{Type of Light |    Torch or Light, !torch 40 20 yes |    Darkvision, !torch 30 0 no |    Enhanced Darkvision, !torch 500 500 no |    No Light, !snuff } But when I run it it just prints the command to the chat log, instead of actually invoking the command. I don't think there are any special characters in there that need to be escaped but just in case I tried escaping the exclamation point, but this did not change the behaviour. What am I doing wrong?

You are likely running into problems with HTML substitutions . You would be much better served by a chat menu: &{template:default} {{name=Type of Light}} {{=[Torch or Light](!torch 40 20 yes) [Darkvision](!torch 30 0 no) [Enhanced Darkvision](!torch 500 500 no) [No Light](!snuff)}} You can put a  /w gm  in front of line 1 if you don't want the players to see the menu.

It might also be something simpler - I havent used the torch script, but some scripts require the ! to be the very first letter on a line. With  Darkvision, !torch 30 0 no | there's a space after the first comma, so a space is the first character on the line.  Changing it to  Darkvision,!torch 30 0 no | is worth a try.

That's good to know. I never use dropdowns for API commands,

All scripts require ! To be the first character in the message, unless they're very poorly written. The message will only have the api type if the first character is a "!".  This will probably work: ?{Type of Light |    Torch or Light,!torch 40 20 yes |    Darkvision,!torch 30 0 no |    Enhanced Darkvision,!torch 500 500 no |    No Light,!snuff }

It was indeed the space between the comma and the exclamation point. Thank you everyone for your help.
