Need help with IFS texture switching

[Benji13]

Hello. I am working on my first mod which adds some simple structural parts. The idea is that in the editor it is possible to switch between multiple textures (using Interstellar Fuel Switch like the colourful fuel lines mod), but I can not get it to work. The default texture and right-click menu work fine, but when you click the button to switch to the next texture nothing happens. I have included screenshots and a link to what I have so far, any help would be much appreciated. Thanks,

Benji13.

P.S. Only the 1.25m version of the disk has the green texture, or should have it.

Images: In the VAB, part works fine, just like any other part.

 

Right-click menu works fine:

When you change to green however, nothing happens:
