MySQL GROUP BY with substring not looping through
===

I am trying to group by a substring.  I only get the one result:

Region = Coastal, Value (R) = 1144900.

I am supposed to get 2 results.

This is my code:

SELECT DISTINCT SUBSTRING_INDEX(`team_name`, '-', 1) AS 'Region', SUM(`opportunities`.`value`) AS 'Value (R)' FROM `opportunities` 
LEFT JOIN cf_type_link_data ON cf_type_link_data.sourceid = opportunities.id
LEFT JOIN cf_lu_type_fields ON cf_type_link_data.fieldid = cf_lu_type_fields.id
LEFT JOIN cf_lu_types_fields_dropdown ON cf_type_link_data.`value` = cf_lu_types_fields_dropdown.id AND cf_lu_type_fields.id = cf_lu_types_fields_dropdown.fieldid
LEFT JOIN `lu_teams` ON `lu_teams`.`contactid` = `opportunities`.`user_allocation`
LEFT JOIN `teams` ON `teams`.`id` = `lu_teams`.`teamid`
LEFT JOIN `lu_opportunity_status` ON `lu_opportunity_status`.`id` = `opportunities`.`status`
WHERE 1 
AND `cf_lu_types_fields_dropdown`.`values` = 'Building Project'
AND cf_lu_type_fields.fieldname = 'Scaffolding Segment'
AND (`opportunities`.`expecteddate` >= '2012-01-01' AND `opportunities`.`expecteddate` <= '2012-07-24')
GROUP BY 'Region' ORDER BY cf_lu_types_fields_dropdown.`values`;

Any help is appreciated.

Thanks!
