Content

Hi Experts,

i need help on outreach mailing

i have created broadcast mailing with merge report but when i see report's preview it is coming as expected but when it send to customer get raw result of report. please see attachment which explains what i am expecting and what sent to customer.

Note: in each column of report has multiple entries and i am exploding it by Custom Script:

$order_number = explode("|",$rows[0][1]->val);

$upc = explode("|",$rows[0][1]->val);

 

 $key = 0; 

    

    for ($k = 0; $k < count($order_number); $k++)

    {

$rows[0][1]->val = $order_number[$k];

$rows[0][2]->val = $upc[k];
