Transparency help please!

[Asasin]

Hey all,

I'm just learning how to work with interfaces and customise them. I'm just stuck on one thing though.

I've read just about every thread with transparency in it and can't seem to figure it out.

Attached are 3 files, helpme.zip (contains my psd), step1.gif (step one of the save process) and step2.gif (step 2 of the save process). Can someone please tell me where i'm going wrong? I'm at my wits end.

I've followed the instructions in this thread to the best of my knowledge, and when i try to save his file it works, but mine just won't.

Cheers,
Matt
