Hi rodiusd,
Ah - now I can see what you have in your form and where the problem is. I've checked the code for the Pane & Panel elements and there is a bug with these elements in Joomla! 3. There isn't a quick fix that I can see so I've passed the info on to Max for him to look at. (The Tabs and Sliders code was changed in the Joomla! 3 core and the way it is now set up means that the structure of the ChronoForms elements needs to be able to distinguish between Tab sets and Sliders sets in a different way.)
You have a couple of choices here: You can use Containers for the Tabs and Sliders - they work OK (with one minor bug in the sliders for which there is a workaround). Or you can use Custom Element elements and build your one tabs and sliders elements - I've put the code for that below. It's not particularly complex.

To start a Tab panel:
<?php
jimport('joomla.html.html.tabs');
echo JHtmlTabs::start('cf_container_some_id');
?>
To end a Tab panel:
<?php
jimport('joomla.html.html.tabs');
echo JHtmlTabs::end();
?>
To start a new Tab inside a Tabs panel:
<?php
echo JHtmlTabs::panel('Tab Label here', 'cf_container_some_id');
?>
The tab will end when a new tab starts or the Tab panel is closed.
To start a Slider panel:
<?php
jimport('joomla.html.html.sliders');
echo JHtmlSliders::start('cf_container_some_id');
?>
To end a Slider panel:
<?php
jimport('joomla.html.html.sliders');
echo JHtmlSliders::end();
?>
To start a new Slider inside a Sliders panel:
<?php
echo JHtmlSliders::panel('Slider Label here', 'cf_container_some_id');
?>
The tab will end when a new tab starts or the Tab panel is closed.
