Name missing from gift organised in advance (6)
I believe the answer is:
preset
'organised in advance' is the definition.
'name missing from gift' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'missing from' is a deletion indicator.
'gift' becomes 'present' (present is a kind of gift).
'present' with 'n' taken away is 'PRESET'.
(Other definitions for preset that I've seen before include "control on channel changer" , "Arranged in advance" , "Initially adjust" , "Pester (anag.)" , "Adjust (control) before use" .)
