Parsing JSON data for video player

I’m using this plugin to parse a JSON feed to put the most recent video in a player, but I’m running into trouble pulling the video URL. Can you tell me what I’m doing wrong?

Here’s the configuration:

API URL: https://wicu.api.franklyinc.com/category/211870/caribbean-weather?clienttype=container.json

Basenode: features

Template:
<video controls=”controls” controlslist=”nodownload” poster=”{subloop:thumbnailimage:1}
{thumbnailimage.filename}{/subloop:thumbnailimage}” width=”100%”>
{subloop-array:group:6}
<source src=”{subloop-array:group.url:6}{3}{/subloop-array:group.url}” type=”video/mp4″>
{/subloop-array:group.url}
</video>
<p class=”video-caption”>Latest Forecast</p>

Number of json-top-level-items to display: 1

In the JSON feed, I’m looking to pull the URL for the third item in the “group,” which is bolded below:

“group”: [
{
“url”: “https%3a%2f%2fwicuhls-video.franklyinc.com%2fz%2fWICU_131020181633082394.smil%2fmanifest.f4m”,
“filesize”: “0”,
“bitrate”: “0”,
“width”: “0”,
“height”: “0”,
“type”: “application/f4m”,
“platform”: “mobile”
},
{
“url”: “https%3a%2f%2fwicuhls-video.franklyinc.com%2fi%2fWICU_131020181633082394.smil%2fmaster.m3u8”,
“filesize”: “0”,
“bitrate”: “0”,
“width”: “0”,
“height”: “0”,
“type”: “application/x-mpegURL”,
“platform”: “mobile”
},
{
“url”: “https%3a%2f%2fvods3-prod.franklyinc.com%2fwicu%2fWICU_131020181633082394AC.mp4”,
“filesize”: “16087829”,
“bitratebits”: “1021621”,
“bitrate”: “1021”,
“width”: “640”,
“height”: “360”,
“type”: “video/mp4”,
“platform”: “mobile”
},
