Rewriting this IF

[MrAdam]

hi. im struggling to create an if statement using "!" to make it the oppsite sort of thing.here's what i have at the moment:

	if (curX >= left && curX <= fmRight) {		// nothing to happen here	} else {		element = document.getElementById('menu');		element.parentNode.removeChild(element);	}

that works fine! .. but.. i don't want to have an else init. i've tried adding an "!" here:

... if !( ...

... but it just said error when i tried to run it?can anybody help?- thanks

You'd want the ! inside the bracket

if(!variable_that_doesnt_exist){   ....do something when it cant find it}

Why not just switch the math operators around though? < left and > fmRight, and use an || instead of &&?
