I have tried everything to correct this error on line $10$ and nothing works! Please help!

I have tried:

return newValue.toFixed$(2)+"$px$"$;

return newValue $+"$px$"$;

return newValue.toString$()+"$px$"$;

return String$($newValue$)+"$px$"$;

newValue.toString$().$concat$("$px$")$;

return $`$$$\{$newValue$\}$px$`$;

return newValue.toString$()+"$px$"$;

None of the above work, I keep getting the same error message on the screenshot.

Complete the JavaScript function addPixels$()$ to calculate the sum of pixelAmount and the given element's cssProperty value, and return the new $"$px$"$ value. Ex: If helloElem's width is $130$px$,$ then calling addPixels$($helloElem$,$ "width", $50)$ should return $130$px $+50$px $="180$px$".$Complete the JavaScript function addPixels $($ to calculate the sum of pixelAmount and the given element's cssProperty value, and

Testing $"$px$"$ in the return value of addPixels $0$

Yours and expected differ. See highlights below. Special character legend

Yours addpixels$()$ does not return a string that consists of a number followed by $"$px$"$

Expected addPixels$()$ returns a string that consists of a number followed by $"$px$"$

Further testing is suppressed until the above passes.
