Trouble including property variables in my codepipeline cloudformation template

Question

I keep having this error CREATE_FAILED               AWS::CodePipeline::Pipeline   CodePipelineTest    Encountered unsupported  property Value   deploying this template

CodePipelineTest:
    Type: AWS::CodePipeline::Pipeline
    Properties:
      Name:
        Ref: PipelineName1
       Variables:
      -
         Name: Version
        Value: test
And also at the build stage of the same template i have been getting error
**The following  pipeline execution  variables are referencing  a namespace that does not exist    **
[{"name":"VERSION","value":"#{variables.version}","type":"PLAINTEXT"}]

Any help will be appreciated

Hello.

You will probably need to change the template as below.  
The template you are using defines something called "Ref:", which is incorrect.  
I think the correct name is "!Ref".  
By setting it to "!Ref", you can pass the "PipelineName1" parameter to "Name".  
```
CodePipelineTest: 
  Type: AWS::CodePipeline::Pipeline 
  Properties: 
    Name: !Ref PipelineName1 # <-- edit
    Variables: 
      - Name: Version 
        Value: test
```
