function wc_authnet_update_error_message1( $error_text, $error_messages ) {

if ( !empty( $error_messages[0]['errorCode'] ) && $error_messages[0]['errorCode'] == 2 ) {
    $error_text = 'Your payment was declined. Please contact your credit card issuer to approve this transaction. Alternatively, select PayPal to pay with your card.\n\nSu pago fue rechazado. Por favor, póngase en contacto con el emisor de su tarjeta de crédito para aprobar esta transacción. Alternativamente, seleccione PayPal para pagar con su tarjeta.';
