the contacts table does NOT have organization type- it has 
 
id, first, last, add , cty, st, zip, tel, fax, dte_created,  email, etc..  but nothing regarding organization type-   I will try you code and let you know- if been on this for the last 30 hours  racking my brain- on a good note i  read and learned alot  since yesterday
 
btw,  I'm using MySQL  and doing this via phpMyAdmin- if it makes any difference
