Help with this script

[canditw]

Need some help with this script, credit to Peopleperson49 for the original script. I've edited abit so that it would give out coins instead of zeny.

What I can't seem to get is to make the jackpot amount more than 10mil zeny. and if it gets past 10.1mil it will reset to 0 zeny. There seems to be a limit to the jackpot amount but i cant seem to find it.
