This message will only appear if someone puts a minus sign in front of the value in question.
To be really specific, the message could say "Minus signs are not allowed" but that sounds a bit clunky to me.

It's anyone's guess whether the user will or will not know what a specific word means, but my bet would be that it's more likely that the average human (not programmer) will know what "negative" means than what >= 0 means.
