cloudformation with ssm key variable

Hi,

I have the following value stored in the SSM key

key: ecrimage-002
value: myimagename

I am trying to retrieve the value by supplying key and referenceid (which is 002) as a "parameter variable" and I cannot seem to get it working in cloudformation.

code is:

"Type": "AWS::ECS::Cluster",  
"Properties" : {  
   "ClusterName" : "{{resolve:ssm:ecrimage:1}}"  

How to pass $referenceid above so I get the value of ecrimage-002 key ? it does not like ecrimage-$referenceid or ecrimage:1}}-$referenceid"

Thanks
