Text Outline is not working

Hello, i want to display some text with a black outline, but everything i tried either doesn't work like i want or doesn't work at all.

The easiest way to do is ( i assume ) is to simply put the Outline Script onto the Object with the Text-components. In the Unity Manual its explained how to use it. For me it doesn't work at all and i can't seem to find any help with this. Its simply just not working. My text looks just like it did before (without any outline). This is what my object looks like:

Plus: I want to change the transparency of the outline later on in an animation. (My text vanishes and so should the outline) I already tried a few other things, for example the code in this Thread, but when i try to change the color.alpha during an animation, it is just getting ignored ingame for no reason. In the editor it works somehow. So my actual text is gone and the Outline stays ...

Any suggestions?
