[SCRIPT] How to achieve this scenario?

[serbusfish]

Ok im a little stuck. I cant get the vase to break when I enter the room. Here is what I have atm:

{
AddEntityCollideCallback("Player", "ScriptArea_2", "stuff", true, 1); //The area is when you enter the room.
{
SetPropHealth("pot_plant_small02_1", 0);
}
}

Now I know more is needed to make the vase break when I enter the area but I cant figure out what, I tried adding the other lines but I get an error and my map wont load :?
