wp-tabbity – anyone used this plugin?

hi im having trouble understanding how to actually get the tabs displayed on my pages. i have created some test tabs but all i get as an output is my code as it is within my page. i have entered the folowing:

{wp-tabbity title="Comments"}
The easiest way to get in touch is by simply leaving comments on the various pages and posts on my weblog, I try to respond to everyone and it's quicker if your query is OK to be viewed by all.
{/wp-tabbity}
{wp-tabbity title="Email"}
{/wp-tabbity}
{wp-tabbitygroup}

where am i going wrong? the plugins site isnt very comprehensive in egards to instructions.
regards
