All you need to get fixed (3)
I believe the answer is:
set
I believe this clue is a triple definition!
'all' is the first definition.
(thesaurus)
'you need' acts as a link.
'to get' is the second definition.
(thesaurus)
'fixed' is the third definition.
(both can mean decided or determined)
(Other definitions for set that I've seen before include "Scenery for play or film" , "Gel; group" , "Where they're filming" , "Scenery etc. for the stage" , "Fixed; collection" .)
