This file attached is the code for x-cart 4.1.9 and for a GBP (UK site) which also includes all the files and patches (plus a read me text file) which i will also display below.

A special thanks to koaloa for a very nice mod.

Go to Admin > General Settings and remove the default alternative currency code.

Copy from (muti_currency_mod.zip) or belowthe following code.

Edit your copy of admin/configuration.php see below.
Note: This file copies the currency rates from the Admin config table to the currencies table on opening or clicking save.

You may not want to copy the full admin/configuration.php (File included in muti_currency_mod.zip), so if this is the case search for:

if ($option == "Security") {
  func_pgp_remove_key();
  $config[$option] = $section_data; # no code after func_pgp_add_key() using these settings
  func_pgp_add_key();
 }

And then AFTER this put in the following code:

// koaconsulting.com - currency mod
 if($option == "Multiple_Currency") {
  // Search through all currency_rate_* variables and update the database accordingly.
  while(list($key,$val) = each($_POST)) {
   if(strstr($key, "currency_rate_")) {
    //echo "found var: $key<br>";
    $code = strtoupper(str_replace("currency_rate_", "", $key));
    //echo "code is: $code<br>";
    $query = "UPDATE xcart_currencies SET rate='$val' WHERE code='$code'";
    //echo "query is: $query<br>";
    db_query($query);
   }
  }
 }
// koaconsulting.com - end currency mod
