Invoice.php and currencies

[clems365]

Hi

 

In my website, I'm using several currencies, so in the invoice.php I have EUR, USD, CA etc... I need to have just one currency in the invoice (USD), I don't how to change the code, I beleive I need to change this line:

 

require(DIR_WS_CLASSES . 'currencies.php');

$currencies = new currencies();

 

But I don't find the solution

 

If somebody can help me, many thanks

 

Best regards
