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

'going on' is the definition.
'lasting' can be an answer for 'going' ('last' can be a synonym of 'go'). I am not sure about the 'on' bit.

'in paris the swindle' is the wordplay.
'in paris the' becomes 'la' ('the' in French).
'swindle' becomes 'sting' (sting is a kind of swindle).
'la'+'sting'='LASTING'

Can you help me to learn more?
