hi,
In table Debtor ,this code is ok!

$DebtorHandle = array('Number' => 110);
$client->Debtor_SetEmail(array('debtorHandle'=>$DebtorHandle, 'value' => 'email'));

But, in table DebtorContact the same code is not.

$DebtorContactHandle = array('Number' => 108);
$client->DebtorContact_SetEmail(array('debtorHandle'=>$DebtorContactHandle, 'value' => 'email'));

How can i update the table DebtorContact's Email ?Can you gave me some ideas? thanks!
