Working with tabs

I am newbie developer and new to this great tool.  I am trying to create a simple tab driven page, but am getting the following error:
Invalid use of RichWidgets\Tabs_ClientSide: You must have at least one tab.  I had inserted 2 containers and defined their "style" as Tabs_TabBoby. 
Make sure the two tab containers are inside another container with style "Tabs_Wrapper" and they each have a "title" extended property.  If your tab containers don't have titles or if they are outside the wrapper you will get this error.

Hope this helps.

Thanks, It was helpful
