variable:scripted vs me...

[Garani]

Hi, everyone!

Maybe, i'm blind to this problem, and the solution us right before my feet, but:

Scripts are nice and they can compute just about anything i can wish for.
But how in the world do i get those infos where i need them?

example:
i want buffbars, that are full and only run down for the last few seconds
i write my script, read buffdurations, compare timeleft to 5 seconds, set my var to the right value, divide it down to a frac, easy this far...
then i define my variable:scripted and link it to the script
but then, how do i get my bar to accept this frac?

I'm confused, tired, feel quite stupid and need help, please?
