How to put negative values?

[Darkfang]

How can i put negative values in the World Editor?
I already checked into the options and i do have the option to do so (its enabled)

But such abilities like (armor bonus item) cant be set into negative values just as my desire. I know there are ways to do, but i dont know those ways... Can you tell me... the WAY?
