Probably not - see below.

You are quoting the entry but including a , before the concat. That
indicates that instead of the quote ', you need to use a backquote ` to
allow the comma to evaluate the (concat ...)  expression at definition
time.

I checked the webpage you refer to and there is a backquote there, so I
can only surmise that you changed it by mistake recently.
