Sheetworker @{button} syntax

I'm trying to write a single sheetworker to work for a large number of buttons, matching each button to a corresponding attr. const lights = [     'lights5a',     'lights5b' ]; lights.forEach(button => {     on(`clicked:${button}`, () => {     getAttrs([`${button}`], v=> { setAttrs({ [`${button}`]: ((+v.[`${button}`] || 0) + 1) % 2                 });             });         });     }); This is currently set up for two buttons, lights5a and lights5b. There is a corresponding attr for each with the same names. When a button is clicked the worker should set the corresponding attr to 1 if it's currently 0 and 0 if it's currently 1. I've copied work I've done (with help!) on previous sheets but haven't used ${button} in getAttrs or after the colon in setAttrs before, so I suspect the error lies in one of those. Can anyone please advise?

The syntax here is incorrect: + v .[ ` ${ button } ` ] It should be + v [ ` ${ button } ` ] And for easier code, could also be + v [ button ] Personally I'd write it a little differently: const lights = [     'lights5a' ,     'lights5b' ]; lights . forEach ( button => {     on ( `clicked: ${ button } ` , () => {         getAttrs ([ button ], v => {             const toggle = + v [ button ] || 0             setAttrs ({                 [button]: 1 - toggle             });         });     }); }); Though for this to work, you must have an action button named act_[button] and an input named attr_[button] (replace [button] as appropriate).

Great, thanks GiGs.
