Please don't (just) say "doesn't work".
It tells us nothing about what you expected to happen and/or what the result is that you currently see, which makes it really hard for us to help you.
(Is it not changing? Is it a pink/black cube etc.? Is it the correct shape with a pink/black texture? etc.)

Also in your case it might just be better to let the game generate the extruded texture from a PNG rather than making a separate model with Blockbench for it.
