Expression days

I tried to show the current day and two upcoming days, so i made a expression. In the facer creater it seemed to work as it showed fri, sat, sun.

But when is saved it and tried to use it as my watchface it did not work, as shown below.

The expression I made is this:
$#DOW#=7?mon:0$|$#DOW#=1?tue:0$ etc, etc

This expression worked perfectly in the facer creator.

Can anyone help me?
