Multiple Alpha Channels question

Sup guys,

I have a quick question about a PSHOP document containing three different alpha channels. So right, I have three different alpha channels each masking a different section of the screen when needed. The "save" file needs to be a TARGA file saved at 32 bit to of course hold the alpha channel. Now when I save the file with the desired alpha channel(out of the three in the channels palette) as a TAGRA it does not take the channel. If it is saved with only one alpha in the pallette(not three, I deleted the other two) it of course holds the channel. Pheww, now is there a way save a targa and get the alpha channel I want without always adding and deleting channels?

Nope.... Targas and Picts only recognize first alpha channel

Two different ways

calculations command or

Cmd click on one, then shift md click on other... then click new channel button to create a channl using current selection
