Alpha Channel not working ?

[higgledyhiggles]

Forgive my ignorance I have an object, unwrapped and a decal graphic but the alpha doesn`t work and leaved the black in ? Tried with a mask with the map set to be the alpha as well, no joy. What am I doing wrong. Couldn`t find anything about it so it must be me ?

thanks

Ok, I`m a doofus, thought so.
Turns out it was so shiny it was reflecting the black environment too much.
Sorry.
