AHA! The brush tool didn't work, but as I was dinking with it, I realized it was not set to "Normal" mode. When I changed the brush took back to "Normal" it works fine! *sigh* Sometimes I'm awfully slow! LOL
Thanks for your help, hatstead! If you hadn't focused me back on the brush tool, off the layer itself, I'd have been banging my head against the wall for another three days!!
