yes, but not nested inside of each other.
the first repeat region will leave the recordset pointer at the end though, so you will need to use this code before the second repeat region to reset the pointer to the beginning:
<?php
mysql_data_seek($rsRecordset, 0);
$row_rsRecordset = mysql_fetch_assoc($rsRecordset);
?>
where rsRecordset is the name of the recordset being used.
