Use store currency BAM

I set up my paypal module to use my store currency for all transactions but it always went to USD because yahoo don't have Bosnian currency is there any way to fix this problem?
I'm afraid not. If Paypal doesn't support it, we can't force them to.
Paypal support it.
But yahoo currency converter not

And I believe it is problem it won't convert to EURO or USD.
I got this error 
Fatal error: Could not update currency value for BAM: No value (http://download.finance.yahoo.com/d/quotes.csv?f=l1&s=EUR&BAM=X) in ~/netsajt/currencies.app/currencies.inc.php on line 45
Are you using an older version of LiteCart. Older versions has an error in the URL string.

The correct URL should be:
http://download.finance.yahoo.com/d/quotes.csv?f=l1&s=EURBAM=X

See admin/currencies.app/currencies.inc.php in LiteCart 1.3.7.

I want to point out I have recceived error reports that forcing store currency in the paypal module doesn't work properly. Let me know if you stumble upon problems with amounts. Test properly before going live.
It works when I click to update currency on admin panel but now when I went to paypal order page it won't take store currency as BAM it took USD it should convert to like $3.23
Let's nail a few factors here first:

What is your store currency? What is the store currency value?

Is the order currency BAM? What is the currency value stored in the order?

Have you enabled Force Store Currency in paypal?
This is my set up for paypal module I tried this add-on too but still won't take it

I don't know why it keep taking USD it should be Total: 6 BAM
What is your store currency? What is the store currency value?

Is the order currency BAM? What is the currency value stored in the order?
Store currency is BAM and value is 1.
Yes order currency is BAM and it save order with correct  currency BAM only problem is paypal won't take it.
I don't know why I can't fine any error everything else works prefect and I really like lite cart it's very fast
