Opacity tag for moon phases not working

Hi everyone,
I have prepared a set of 28 images that show the various moon phases.
I’m thinking about two possible solutions here:

The easy one: show hide image with each passing moon phase. I prepared this tag:
([mp]==0)?100:0
This is not working in the test pane to the right.

The hard one: Show the image for the first half of the phase, then dim it out during the next half, while at the same time fading in the image for the next phase, and so on.

Again: something seems wrong with the first tag. And I have absolutely NO idea how to set up a tag for the second solution…

ANY help would be very much appreciated!!!

Hello,

I think that will answer all your questions.
