newbie function question

Hello all, new to programming and php. please help. I'd like to put the following into a function and am lost on how to go about it. thanks $result = mysql_query ("SELECT * FROM current_holdings"); if ($row = mysql_fetch_array($result)) $ttl_rec = $row["amount"] * $row["price"] - $row["commission"]; $ttl_gain = $ttl_rec - $row["total_spent"]; then currently i put that into the table. (which does the job) <td div align=center><?php echo $row["ticker"]?></td> <td div align=center><?php echo $row["amount"]?></td> <td div align=center><?php echo $row["price"]?></td> <td div align=center><?php echo $row["commission"]?></td> <td div align=center><?php echo $row["total_spent"]?></td> <td div align=center><?php echo $ttl_rec ?></td> <td div align=center><?php echo $ttl_gain ?></td> Sincerely, Cory
