I am trying to create an effect on WIP TARDIS Panel that spits out multiple lava particles (/particle 27) and makes a lightning strike sound. Question 1: How do you play multiple commands to happen at once, when I try to add multiple, it just says invalid perameters. Question 2: Can someone give me a few commands and sounds to help me with other effects.

Thanks in advance :)
