Clicking a button OUTSIDE an iframe

Hey all i am trying to "click" a button thats outside of the iframe (on the main page)..

I can not seem to get it working... here is the code

Basic.html
===============
<iframe width="600px" height="250px" id="infoFrame" name="infoFrame" src="test.html" scrolling="no" frameborder="0"></iframe>
<input name="closeSlide" id="closeSlide" type="button" onclick="$('.btn-slide2').click();" />


test.html
===============
<input name="close" type="button" onclick="parent.document.getElementById('closeSlide').Click();" />

Any help would be awesome!

David

<input name="close" type="button" onclick="parent.document.getElementById('closeSlide').onclick();" />
