This is the serverside script, it is not tested
addEvent('onPlayerPayfine', true)
addEventHandler('onPlayerPayfine', root,
function(thePlayer)
if( getPlayerWantedLevel( thePlayer ) > 0) then
setPlayerWantedLevel( thePlayer, 0)
outputChatBox( 'you have done the fine !!', thePlayer, 255, 255, 0, false );
else
outputChatBox( 'An error occurred while fining !', source, 255, 0, 0, false );
end
end)
Let me know if it works
