[Plugin: Event manager] Extra field i Attendeeslist

I’m have a Plugin ‘Cimy User Extra Field’ and i add an extra field to a user, now i would show that field together with the user who has a booking in the placeholder #_ATTENDEESLIST.

e.g User/’MyValue’

How do i add my value in to the array below in the template file when my value is in another db-table.

$people[] = $EM_Booking->get_person()->ID ;

The ID for the User is the same as USER_ID in CUEF_table and the column my wanted text is in called VALUE.

Any hint? i’m a newbee in arrays 😉
