another problem with var types.

[proseLA]

frequently, when users want to zero something out, they just delete the field so that it is now blank. EO does not handle these situations well at all.

if one blanks out the shipping cost, you get to here:

edit_orders/YOUR_ADMIN/includes/classes/editOrders.php

Line 280 in 769b2cc

$shipping_cost = $this->eoRoundCurrencyValue($current_total['value']);

and i have no idea what that method does, but the value starts at blank and it returns a blank value.

so now you update to a blank value here:

edit_orders/YOUR_ADMIN/includes/classes/editOrders.php

Line 287 in 769b2cc

$order->info['shipping_cost'] = $shipping_cost;

and then this chokes here:

edit_orders/YOUR_ADMIN/includes/classes/editOrders.php

Line 379 in 769b2cc

$shipping_tax = $this->eoRoundCurrencyValue(zen_calculate_tax($order->info['shipping_cost'], $tax_rate));
