admission fee

I'm a little stuck... Click here to teach me more about this clue!

'an incoming charge' is the definition.
'admission fee' can be an answer for 'charge' (admission fee is a kind of charge). I am not certain of the 'an incoming' bit.

'incoming charge' is the wordplay.
'incoming' becomes 'admission' (admission is a kind of incoming).
'charge' becomes 'fee' (fee is a kind of charge).
'admission'+'fee'='ADMISSION FEE'
