Perch every

Hi

i want to use perch:every to create a slideshow

Each slide has 3 divs in it.

How can i do this?

I tried:

<perch:before><div class="cycle-slide"></perch:before>
<perch:every count="3"></div><div class="cycle-slide"></perch:every>
<div class="event">
   <span class="date"><span class="day"><perch:events id="eventDateTime" format="j" /></span>
   <br /><span class="month"><perch:events id="eventDateTime" format="%b %Y" /></span></span>
   <span class="detail"><perch:events id="eventTitle" /></span>
</div>
<perch:every count="n+3"></div></perch:every>

but the first slide only contains 2. then it works every 3...

Thanks
