error in sql syntax - orders are not showing up

[markmunyan]

Some orders show up and some do not. This i know because customers must log in and payments are made.

 

 

This is last error message when selecting customers order button...

 

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-20, 20' at line 1

 

select o.orders_id, o.customers_name, o.customers_id, o.payment_method, o.date_purchased, o.last_modified, o.currency, o.currency_value, s.orders_status_name, ot.text as order_total from orders o left join orders_total ot on (o.orders_id = ot.orders_id), orders_status s where o.customers_id = '24' and o.orders_status = s.orders_status_id and s.language_id = '1' and ot.class = 'ot_total' order by orders_id DESC limit -20, 20

 

Thanks in advance and appreciate help,

Mark
