[SCRIPT] Adding 3 Items to Acid Container then Pickup

[Damascus]

You'll need to use Variables. For each callback where you add a chemical, you'll need to add 1 variable of your choice (AddLocalVar) and an option for activating the final callback. It should be an "if" statement that will only activate when your variables are at 3. That should allow you to add the chemicals in any order, and the final chemical will let you use that final callback.

I probably worded that in the most confusing manner possible as I'm very sleepy.
