Eric's not able to arrange the festivities (12)

I believe the answer is:

celebrations

'the festivities' is the definition.
('celebration' can be a synonym of 'festivity')

'eric's not able to arrange' is the wordplay.
'to arrange' is an anagram indicator.
'erics'+'not'+'able'='ericsnotable'
'ericsnotable' is an anagram of 'CELEBRATIONS'.

(Another definition for celebrations that I've seen is " Festivities".)

I've seen this clue in The Irish Independent.
