Running total in custom invoice....
 

Editing my order_data.tpl file to create a custom invoice I am trying to get a running total using $products[prod_num].total, ie;

quantity---description----price each-----total
5-----------cd-roms--------бё1.00---------бё5.00
2-----------books----------бё0.50----------бё1.00

I can't get the total column in the invoice, ie;price each * quantity.

Anybody got any ideas?

at the end of each loop (before you display the total, put in :

{assign var="runningtotal" value=+$products[prod_num].total}

Then display $runningtotal

This might do it :) haven't tested it though.

For ideas on how this might work look at the bestsellers template.
