Copy attribute vm.name to another attribute vm_new.name

Hi Folks,

I am trying now to generate a new attribute out of an old one.

I want the attribute vm.name which is "Test_Archive" in a new attribute vm_new.name "Clone_Test_Archive". I tried the following code:

new_vm_name.name = "Clone_"+vm.name

I get an error: TypeError: Cannot set property "name" of null to "Clone_Test_Archive"

Where is my error?

Thanks a lot.

Chris
