So I have this code. The two security groups App1 and Shared-Zones1 initialized fine but then when it comes to app2 trying to spawn, it will throw an error saying that Shared-Zones1 doesn't exist. I can see that it does and its initialized? I've trolled through Google and I can't find anything I need, the documentation doesn't really help me out either. Help please it is driving me mad!
