the button creates this link....

/super_batch_forms.php?status=2&ot_sign=1&checked=0'

which doesn't work, but if i type this url into the browser

/super_batch_forms.php?start_date=&end_date=&status=2&products=&customers=&countr ies=&payments=&ot_sign=1&order_total=&search=&oid_range_first=&oid_range_last=&c hecked=1

it works, exactly the same is true for batch status update
