Hero editor...def and attck rating

[ForcesOfGood]

Hi i'm still kind of new to diablo 2 and hero editor. I've been trying to make a char that is real good at dueling. I've downloaded char on exonfluxx.com but hell there no good. I've been on a loosing streak for like 3 monthes now and I havn't beaten anyone in a duel. I die all the time. I've been trying to get my def up to 2 billion and my attack rating up as high as I can get it. when I make charms to do that though they always make my def go negative and when i take away a few of them it goes positive but still very low! I think my def right now for my pally is like 2445688 and I can't get it any higher or it goes neg. Plus my attack rating is real too

can anyone help me out? or tell me what i'm doing wrong. If you need any other info just ask me ok.
