Hi Therese,

It's just yaml, so I sometimes head over to
http://yaml-online-parser.appspot.com/ and dump my template in there
and tells you what is wrong.

Basically you are putting your parameter values in the wrong place.

instead of:
parameters:
   key_name: mykey
     type: string
     description: Name of keypair to assign to servers
remove the "mykey" so it is back to:

parameters:
   key_name:
     type: string
     description: Name of keypair to assign to servers


Then start the template like this:

heat stack-create mystack --template-file=/scripts/servers_in_existing_neutron_net.yaml -P "key_name=mykey;image=Ubuntu;flavor=m1.small"

Hope that helps
