Add PayPal fee

thank you!
yes, I need these details ( table prefix can be different).

please, replace code wit this version

add_filter('woe_get_order_value__ppcp_paypal_fees',function ($value, $order,$fieldname) {
$data = maybe_unserialize($value);
if( isset($data['paypal_fee']['value']) )
  $value = $data['paypal_fee']['value'];
return $value;
},10,3);

You’re welcome
