Objet : _expression_ needed

Hi all

  Just a quick bit of math needed (my brain is tired after the 3 hr drive
home in the snow last night)

I want to use an _expression_ to make a composite node have Input 1 go from a
value of 100 to 0 WHILE
Input 2 goes from a value of 0 to 100 (a transition)

I would like to do this with a "transition" input on my Master PPG composite
node (ie. I just want to set the opacity on the PPG at start to be 0 and at
end to be 100 and have the _expression_ change the input values on my main
composite node)

I hope that is fairly clear.

Input 2 on the main node is a straight copy from the Master PPG.

Cheers
