IF AND statement in crimson complex code

I'm trying to do an if statement relying on two Boolean values;
IF (tag1) AND (tag2) RETURN output 1
ELSE IF (tag1) RETURN output 2
ELSE IF (tag2) RETURN output 3
ELSE RETURN output 4

I just don't know how to put that AND from the first line into Crimson code

Replace AND with &&.

Thanks that worked
