Hi Conall,
In your example, I see the name (dynamicContent) in your variable does not match the name used in the dynamic feed(devDynamicContent)... I wonder if it is just a typo when you copy and paste the codes?
I think the correct codes should probably look like:
<script type="text/javascript">
var extra_frame = (devDynamicContent.Flybe_1705_dynamic_300x250[0].extra_frame);
console.log(extra_frame);
</script>
Also, I think you have to put you variable after the Dynamic feed, for example, in code view:
......
<script type="text/javascript" id="h5GeneratedCode">
Enabler.setProfileId(1234567);
var devDynamicContent = {};
......
......
......
Enabler.setDevDynamicContent(devDynamicContent);
</script>
......
<script type="text/javascript">
var extra_frame = (devDynamicContent.Flybe_1705_dynamic_300x250[0].extra_frame);
console.log(extra_frame);
</script>
Hope this helps.
Thanks,
