Multiple Font issue

[rav3n256]

I've been struggling with fonts for a little while, so I'm hoping for some help.  I've got 3 custom fonts and I'm trying to put them all in a single font atlas.  I have the fonts paired with it's appropriate text file.  I'm able to successfully create the first font in an atlas using the Font Maker tool, but when I repeat the process again with the same atlas, it throws this error "Font 'something' must be created with only 1 texture, not 2".  From my readings, I can put all the fonts in 1 atlas, but must have multiple UIFont prefabs to use the UILabel.  If this is wrong, please tell me. Any suggestions.

Just to check out the process, had some issues there too when started using NGUI.
In Font Maker:
- Drag the correct .txt to the Font Data -field
- Drag corresponding png to the Texture -field
- In Output, change to font name to represent the font you're importing. NGUI doesn't change to font name for you, and I suppose this is what you might have forgotten after importing the first font
