You just need a backquote here instead of a plain quote. A good rule of
thumb is that if you climb up (using backward-up-list, C-M-u) from a
comma, there should always be exactly one corresponding backquote per
comma. In this case you had two commas, but only one backquote.

This works too, though it's a bit clunky.

FYI, you really mean a quoted symbol, not a string literal.
