Hi all this was my original thread which I thought I got an answer for but still having the same problem:
This still isn't working, when I try the solution I was given the only thing that happens is it overlays the A, it still appears on the red background and anything behind it.
Hi all sorry never mind. For some strange reason I was clicking the little arrow and selecting "Release/Create Clipping mask" and it wasn't working however I tryed going to object>clipping mask>make and it worked!
Clicking the little arrow where? The flyout menu in the transparency panel lets you "make opacity mask" which, while sharing some of the capabilities, is a very different thing than a clipping mask.
