Get value

Hi, I installed your plugin and the extra fields are saved into the tables wp_cimy_uef_fields. However if I call

$referrer_id = get_cimyFieldValue( $user_id, 'referrer_id')

No value is returned. I printed the composed query and it prints this:

SELECT efields.LABEL, efields.TYPE, data.VALUE FROM wp_15_cimy_uef_data as data JOIN wp_15_cimy_uef_fields as efields ON efields.id=data.field_id WHERE efields.name='REFERRER_ID' AND data.USER_ID=16 AND efields.TYPE!='password' AND (efields.TYPE!='radio' OR data.VALUE!='')"

It seems to search the value in the specific blog. Did i make any mistake in installing the plugin or is a bug?
