Here is what I found in code regarding the division by zero. I'm not sure what to change it to. Can anyone help?

'customer_id'] . "'");

if ($group_query->fields['customers_group_pricing'] != '0') {

$group_discount = $db->Execute("select group_name, group_percentage from " . TABLE_GROUP_PRICING . "

where group_id = '" . (int)$group_query->fields['customers_group_pricing'] . "'");

$gift_vouchers = $_SESSION['cart']->gv_only();

$discount = ($order_total - $gift_vouchers) * $group_discount->fields['group_percentage'] / 100;

$od_amount['total'] = round($discount, 2);

$ratio = $od_amount['total']/$order_total;

/**

* when calculating the ratio add some insignificant values to stop divide by zero errors

Your welcome but did this thread resolve your issue?

Hello,
I finally had time to make this change. The above instructions did resolve that issue. The problem now is I'm receiving these parse errors when I make changes. When I open the .php files, make the change, and upload, the formatting messes up and the .php essentially becomes a continuous word wrap document with no hard returns. ? I'm receiving this error now:

Parse error: syntax error, unexpected T_CLASS in /home/annettes/public_html/includes/modules/order_total/ot_group_pricing.php on line 8

1) how do I correct this error? and 2) how do I correct the formatting problem when uploading the new .php?
