[SOLVED] Auto Action Plugin is not assigning usergroup

I follow this tutorial to assign user to selected user group in registration form. But all registered users are assigned to 'Customer' group even though I chose the 'Partner' group in registration form.

I am using joomla 3.1.5 and CB 1.9.

Here are screen shots of my configurations.
Is there something I missed?

I could not added screen shots more than two.

Here are Auto Action Plugin configurations:

Published = Yes
Title = Customer Group Assignment
Type = Usergroup
Triggers = onAfterUserRegistration
User = Automatic
Access = Everybody
Conditional = [cb_usertype] Equal To Customer
Usergroup Action
Mode = Add Usergroups
Groups = Customer

Published = Yes
Title = Premier Reseller Group Assignment
Type = Usergroup
Triggers = onAfterUserRegistration
User = Automatic
Access = Everybody
Conditional = [cb_usertype] Equal To Partner
Usergroup Action
Mode = Add Usergroups
Groups = Premier Reseller

Problem solved. Somehow plugin was disabled so it is not working.
