We have not found the cause of the issue yet.
to troubleshoot this issue try finding the following code on the confirm page:
$WA_editCmd = mysql_query($WA_sql, $WA_connection) or die(mysql_error());
and change it to:
$WA_editCmd = mysql_query($WA_sql, $WA_connection) or die($WA_sql);
you should find that code about 4 or 5 times. this will cause the SQL that is generating the error to be written to the screen
Post pack the results and a copy of the confirm page and I will look into it.
