CB Subs Plan Modules

I've created 2 modules ( CB Subscriptions module to be used with CBSubs ) But can't for the life of me get them displayed in any module position!! Nothing appears, not even the module title.
There doesn't appear to be any option to select a specific plan to display either. Is this what this module is meant to be used for?
How do I go about displaying individual plans in a module?

Many thanks,
Tony.

It's meant to display similar results as viewing the plans page or subscription tab. So it should show plans available to you like either of those given you've set all of its displays to Yes. Does the plans page and/or your subscription tab display anything?

OK. So now I understand what the module is for, which isn't what I want.
I was hoping to display individual plans to non-logged in users who could then sign up in the module, similar to what is displayed when you select the menu item CB Paid Subscriptions. This way I could display the same result it get on that page in other pages without having to create a menu link for them.

I've tried displaying the menu item URL for the plan in a Custom module using an iFrame, however it displays the whole page. Is there some what I can simply display the plan only?
index.php?option=com_comprofiler&view=pluginclass&plugin=cbpaidsubscriptions&do=displayplans&plans=2

CBSubs provides substitutions via its system plugin anywhere Joomla content plugins are supported. So for example in a CB Content Module with content prepare parameter enabled. Review the CBSubs system plugin description within Extensions > Plugins for usage information. You can substitute in a plans name, description, price, button to buy a the plan, etc.. That's likely the best way to have what you're wanting. If you still want to use an iframe (I don't recommend this approach; the links will likely just navigate the iframe around) add &tmpl=component to the URL.
