Im not sure what to include here so I will show those specific areas...

<?php
		$con=0;
		while($row = mysql_fetch_array($movResults)){	
			if($con == 0) {
			echo "<div class=\"container\">
			<div class=\"row\">
			<div class=\"fourcol\">
				<div class=\"movImg\">
					<img src=\"images/".$row['products_thumb']."\" alt=\"".$row['products_name']."\">
			</div>
        	<div class=\"movTxt\">
            	<h3>".$row['products_name']."</h3>
            	<p>".$row['products_price']."</p>
								<a href=\"productdetail.php?id=".$row['products_id']."\">View Product.....</a>

        	</div>
        </div>";
		$con++;
			}else if($con == 1){
			echo "<div class=\"fourcol\">
				<div class=\"movImg\">
					<img src=\"images/".$row['products_thumb']."\" alt=\"".$row['products_name']."\">
			</div>
        	<div class=\"movTxt\">
            	<h3>".$row['products_name']."</h3>

								<a href=\"productdetail.php?id=".$row['products_id']."\">View Product.....</a>

        	</div>
        </div>";
		$con++;
			}else if($con == 2){
			echo"<div class=\"fourcol last\">	
			<div class=\"movImg\">
					<img src=\"images/".$row['products_thumb']."\" alt=\"".$row['products_name']."\">

		</div>
		<div class=\"row\">";
		$con = 0;
			}

		$numRows = mysql_num_rows($movResults);
		$div = $numRows%3; 
	
		if($div==1){
