Hi all,
Sorry if this has been posted somewhere already, but I've spent most of the morning looking for an answer and cannot find anything specific to this issue.

I've followed the procedures on installing qbi_v3_21b_zen and I am now at the point of setting up the initial configuration options. After configuring all the option and clicking on "update" to submit the form, I get the following message:

Code:
Notice: Query failed: Incorrect integer value: '' for column 'tax_lookup' at row 1 SQL: UPDATE qbi_config SET qbi_qb_iso2='US',qbi_qb_subver='1',qbi_qb_addr='0',qbi_output_fmt='iif',qbi_file_date='1',qbi_dl_file='1',qbi_prod_rows='5',prods_sort='0',item_width='48',qbi_log='1',orders_status_import='2',qbi_status_update='1',qbi_cc_status_select='2',qbi_mo_status_select='1',qbi_email_send='1',qbi_cc_clear='0',orders_docnum='%I',orders_ponum='%I',cust_nameb='%C10W-%I',cust_namer='%L10W-%I',cust_limit='0',cust_type='',cust_state='1',cust_country='0',cust_compcon='1',cust_phone='1',cust_default='0',cust_default_name='',invoice_acct='Accounts Receivable',invoice_salesacct='Undeposited Funds',invoice_toprint='1',invoice_pmt='1',invoice_termscc='PayPal',invoice_terms='Check',invoice_rep='',invoice_fob='',invoice_class='',invoice_comments='1',invoice_message='Thank you very much!',invoice_memo='',item_acct='Sales',item_asset_acct='Inventory Asset',item_class='',item_cog_acct='Cost of Goods Sold',item_cart_lang='0',item_match_i in C:\apache\htdocs\store\ADMIN_NAME_REMOVED\includes\classes\qbi_mysql.php on line 119
Additional Info:
* Apache/2.2.9 (Win32) PHP/5.2.6
* MySQL client version: 5.0.51a
* PHP extension: mysql

Does anyone have any pointers on where to start looking?

Thanks
