Hit Test Problem, Please help

if (_hero.hitTestObject(_mountain))
trace(“they hit”);


if (_hero.slash.hitTestObject(_enemy))

				trace("they hit");
				_enemy.visible = false;

i know that the second if statement is wrong cuz I definitely don’t know the right code
when the hero attacks/slash the enemy the enemy will disappear .

sorry for disturbance but i hope you guys can help .
