component in sidekick, but will not appear on page

Hello, currently at a loss as to why a component I have created which appears in the Sidekick is not working. I have created a new parsys area on a page in AEM, I can drag other components into this area then edit their values, but the new component when I drag into the parsys area nothing happens. I initially copied an existing component, one which worked, so it has the same crx properties, though with different title, description etc. I have checked the properties via CRX and the properties all look similar to those of components which work, so at a loss as to why this newly created one does not work. I have read through online documentation no wiser, any ideas.
