[Sheet Workers] Using variable names in setAttrs?

I am attempting to set an attribute dynamically, but it seems like the compiler does not want to parse the combined string as a string, and instead stops when I get to "+". How do I fix this? I considered storing the string in a variable, but then realized that the setAttrs function would not look for the variable, but a (nonexistant) attribute of that name. Here is my code (keep in mind that most of it is omitted for brevity's sake; while referenced in here, it doesn't pertain to my problem at the moment): on("change:repeating_weapons:Uses", function(eventInfo) {     console.log(eventInfo.newValue)     if (eventInfo.newValue === "0"){         console.log("Broken")         let RID = eventInfo.sourceAttribute.slice(18,38) //This gets the repeating row ID of the changed attribute         getAttrs(["repeating_weapons_"+RID+"WName"], function(v){             setAttrs({                 "repeating_weapons_"+RID+"_WRank": "UU", //here is where the error is                 "repeating_weapons_"+RID+"_WName": "Broken " + v["repeating_weapons_"+RID+"_WName"]             });         }     } });

When setting the properties of an object the way you are doing, you must use static keys. To use dynamic keys, try this: on("change:repeating_weapons:Uses", function(eventInfo) {     console.log(eventInfo.newValue); setObj = {}; //create an empty object     if (eventInfo.newValue === "0"){         console.log("Broken")         let RID = eventInfo.sourceAttribute.slice(18,38) //This gets the repeating row ID of the changed attribute getAttrs(["repeating_weapons_"+RID+"WName"], function(v){ setObj["repeating_weapons_"+RID+"_WRank"]="UU"; //set the "repeating_weapons_"+RID+"_WRank" key of that object to "UU" - It was undefined before. setObj["repeating_weapons_"+RID+"_WName"]="Broken " + v["repeating_weapons_"+RID+"_WName"]; //same as above             setAttrs( setObj );         }     } });

Can you just use square brackets like so: ? on("change:repeating_weapons:Uses", function(eventInfo) {     console.log(eventInfo.newValue)     if (eventInfo.newValue === "0"){         console.log("Broken")         let RID = eventInfo.sourceAttribute.slice(18,38) //This gets the repeating row ID of the changed attribute         getAttrs(["repeating_weapons_"+RID+"WName"], function(v){             setAttrs({                 ["repeating_weapons_"+RID+"_WRank"]: "UU", //here is where the error is                 ["repeating_weapons_"+RID+"_WName"]: "Broken " + v["repeating_weapons_"+RID+"_WName"]             });         }     } });

G G's method with square brackets works (though your original code is missing a closing bracket after the getAttrs, which is still present in both Scott's and G G's corrected code, bolded in my version). However, if you only need to set attributes in the same repeating row, you do not need to reference the rowid explicitly at all: on("change:repeating_weapons:uses", function(eventInfo) {     console.log(eventInfo.newValue);     if (eventInfo.newValue === "0"){         console.log("Broken");         getAttrs(["repeating_weapons_WName"], function(v){             setAttrs({                 "repeating_weapons_WRank": "UU",                 "repeating_weapons_WName": "Broken " + v["repeating_weapons_WName"]             });         } );     } });

That really helps. Thank you!

Another point: You can use template literals as property keys in an object literal, eg: setAttrs({ `repeating_weapons_${RID}_WRank`: ..., `repeating_weapons_${RID}_WName`: ..., });

Oh, that's nice, didn't know that Brian!
