Pass capture variable to json

I am capturing an input from the Capture into a variable. I want to use that variable as part of a display response. Variable is called {message}. Here is the JSON I’m trying to use:
{
“headlineTemplateData”: {
“type”: “object”,
“objectId”: “headlineSample”,
“properties”: {
“backgroundImage”: {
“contentDescription”: null,
“smallSourceUrl”: null,
“largeSourceUrl”: null,
“sources”: [
{
“url”: “https://d2o906d8ln7ui1.cloudfront.net/images/templates_v3/headline/HeadlineBackground_Dark.png”,
“size”: “large”
}
]
},
“textContent”: {
“primaryText”: {
“type”: “PlainText”,
“text”: {message}
}
},
“logoUrl”: “https://d2o906d8ln7ui1.cloudfront.net/images/templates_v3/logo/logo-modern-botanical-white.png”,
“hintText”: “To exit, say, Alexa, Exit.”",
“welcomeSpeechSSML”: “<amazon:emotion name=‘excited’ intensity=‘medium’>OK. I’ll display on a walk.</amazon:emotion>”
},
“transformers”: [
{
“inputPath”: “welcomeSpeechSSML”,
“transformer”: “ssmlToSpeech”,
“outputName”: “welcomeSpeech”
}
]
}
}

The variable wants to be the text that is displayed. What am I missing?

This seems like it should be pretty easy, but I sure can’t get it to work.
