need help

I have Mysql set up on the same machine as the apache server. There is a database name inventory_db with a table product_info which have the two row id and name. I know there are three records in the table. However when ever I place this script below into a webpage I get just a blank page. What can I do to correct it. Thank you <? php # connect to mysql $conn= @mysql_connect("localhost", "root") or die ("Err:conn"); #select the specified database $rs= @mysql_select_db("inventory_db", $conn) or die("Err:Db"); #Create the query $sql= "select id, name from product_info"; #execute the query $rs= mysql_query($sql, $conn); #write the data while ($row=mysql_fetch_array($rs) ) { echo("Product ID: " .$row["id"]); echo(" Product Name: " .$row["name"] "<br>"); } ?> /*" The gospel is meant to comfort the afflicted and afflict the comfortable."
