Need Help with Action Requirements on Items

[Morkilimus]

So I'm working on a way to collect water in empty jars when it's raining. Since there is no way (that I know of) to check for rainfall, I want to check two separate requirements for the action.

 

1.) check is user has the wet buff

2.) check if the user is outdoors.

 

So, I attempted writing in these two requirements on empty jars, and created a barrel that will act as the target block. The idea is that you place the barrel outdoors, and when itآ’s raining (you are wet AND not sheltered) then you can fill your jars from the barrel.

 

But when I list these two requirements, it seems that only one of them needs to be met in order to carry out the action, when in fact I want BOTH requirements met.

 

Does anyone know how to make this happen?
