Right i know that...

I'm sorry my termonology is crap...

Not reset opacity

like Re Define "A" Is what i meant....
I think this is a wonderful example of how there are many ways (I count 3 in this case) to do one simple thing

1) set opacity value as a number then subtract .05 from it
2)Mybase.Opacity-=0.5
3)and if anyone followed the one that i thought was the only way from the begnning
