Answer 1

The problem lies here:
mysql_free_result($storeresults);
?>
<table border="0">
  <tr>
    <td>str_id</td>
    <td>str_name</td>
    <td>sale_begin</td>
    <td>sale_end</td>
  </tr>
  <?php do { ?>
    <tr>
      <td><?php echo $row_storeresults['str_id']; ?></td>
      <td><?php echo $row_storeresults['str_name']; ?></td>
      <td><?php echo $row_storeresults['sale_begin']; ?></td>
      <td><?php echo $row_storeresults['sale_end']; ?></td>
    </tr>
    <?php } while ($row_storeresults = mysql_fetch_assoc($storeresults)); ?>
</table>
mysql_free_result() is destroying the recordset resource before the repeat region.
If you delete mysql_free_result($storeresults); it should work.
Dreamweaver always puts mysql_free_result() below the closing </html> tag, so it looks as though you have accidentally moved it. When working with server behaviors, it's important to remove them cleanly by clicking the minus button in the Server Behaviors panel. Otherwise, you can be left with stray bits of code that cause problems like this.
