Hello,

I am trying to launch/create multiple instances and attach multiple  
volumes with a loop but not having much luck. I can get it to work if  
I define each instance/volume but who wants to do that? Ideally I  
would set a var that says something like make 100 instances. Below is  
an example of what I currently have. How to I transfor these into  
loops?
