[Sheet Workers] Need help when using GreaterThan/LessThan/GreaterOrEqual/LessOrEqual

No matter what I do, my script will not work when trying to use the aforementioned comparisons. on("change:Power", function() {     getAttrs(["Power", "PowerRank", "PowerMod"], function(values) {         var modifier = Math.floor(parseInt(values.Power) / 100);         var letter = "I";         if(parseInt(values.Power) < 100) {letter = "I"};         if(parseInt(values.Power) >= 100 && parseInt(values.Power) < 200) {letter = "H"};         if(parseInt(values.Power) >= 200 && parseInt(values.Power) < 300) {letter = "G"};         if(parseInt(values.Power) >= 300 && parseInt(values.Power) < 400) {letter = "F"};         if(parseInt(values.Power) >= 400 && parseInt(values.Power) < 500) {letter = "E"};         if(parseInt(values.Power) >= 500 && parseInt(values.Power) < 600) {letter = "D"};         if(parseInt(values.Power) >= 600 && parseInt(values.Power) < 700) {letter = "C"};         if(parseInt(values.Power) >= 700 && parseInt(values.Power) < 800) {letter = "B"};         if(parseInt(values.Power) >= 800 && parseInt(values.Power) < 900) {letter = "A"};         if(parseInt(values.Power) >= 900) {letter = "S"};         setAttrs({             PowerMod: modifier;             PowerRank: letter;         });     }); });

when i pasted it into jslint there was a weird invisible character on your first line with "on" That might have been a side effect of cutting and pasting But the  issue is your call to setAttrs, you have semicolons where you need a comma: setAttrs({ PowerMod: modifier, PowerRank: letter });

Aha! Thank you kind sir.

While the code should work with Chris's fix, I'd suggest that you replace the multiple if statements with else if statements, as you then wouldn't need to check the lower bounds. Probably not a big issue, but just a suggestion.
