How do i put an if statment on every third record??

eg every third record i need to print some extra code like <br /> for example

Do I add a counter to the php(below)
function LatestExhibitions(){
return DataObject::get("ExhibitionPage", "ParentID = $this->ID", "`ExhibitionPage`.ID DESC", "", 9);

or to the control

<% control LatestExhibitions %>

<% end_control %>

A DataObject within a DataObjectSet has access to it's current iterator position through Pos().

Therefore, in ExhibitionPage add the following method:

function MultipleOf($mod, $offset = 1) {
	return ((($this->Pos() + $offset) % $mod) == 0);

Then, in your template, you can do (for example):

<% control LatestExhibitions %>
	<% if MultipleOf(3) %>
		<br />
	<% end_if %>
<% end_control %>
