How to display currencies not supported (e.g. zł or kr)

By default, One Stop Order Processing can't show all currency symbols on the invoice. If you need to add in currencies not supported you should use the following approach.

1. Amend the invoice template you are using (In the Invoice Options tab in the Options).
2. Find the fields where you want to display the correct currency symbol (e.g. Grand Total, which would be the 
[%ORD_GRAND_TOTAL%] macro)
3. Change the macro to the following:

For Swedish Krona
#!#[%ORD_GRAND_TOTAL%][$][0][1] [=]k[kr#!#[%ORD_GRAND_TOTAL%][$][1][30]#!# ][[%ORD_GRAND_TOTAL%] ]#!#

For Polish Zloty
#!#[%ORD_GRAND_TOTAL%][$][0][1] [=]Z[ zł#!#[%ORD_GRAND_TOTAL%][$][1][30]#!# ][ [%ORD_GRAND_TOTAL%] ]#!#

For more general setting of a different currency you can use the currency for the product and use the 
[%PRODUCT_CURRENCY%] macro
