[Uitat]

ok so i had tried what you suggested, and came up with bad juju, it litteraly cut my current to next level in half and thats all

so here we go again i made some changes, just to get out of the bug fix coding as i was doing adn renamed things to what i though would be ok

im going to post the entire script here so all events are shown

what is happening.
before the fix, stack overflow issue

after the fix
no more stack overflow Errors
However

my druid shows 4 Mil / 39Mil which is correct
Pally shows 900 Mil / 4 Bil which is correct
Warrior shows 100 / 300 which is correct
and so on

my Desired Result if artifact xp to next and artifact currently in my stash

is more then 1,000,000
please for the love of god add a period and 2 digits behind.
i.e. 1.05 mil , 1.15 bil, 4.05 bil, 900 mil, 45 bil and so on

here is all of my code
someone please rip me appart and tell me what stupid crap ive done cause im goin batty
