Exploding doors

[giacomo9]

The player has an explosive potion. When you use it on the door, they explode - how to do it? I have a script for this, but it shows the information "Cannot use this item in this way"...
Here's the script:
("Completed" - that is exploding potion; "cheryl" - this is normal door; "cherylBroken" - this is broken door)

AddUseItemCallback("", "Completed", "cheryl", "Boom", true);

void Boom(string &in asItem, string &in asEntity)
{
SetEntityActive("cheryl", false);
SetEntityActive("cherylBroken", true);
PlaySoundAtEntity("", "06_break_wood.snt", "cheryl", 0, false);
RemoveItem("Complete");
}
