Google Spreadsheets formula to extract and convert currency from EUR/USD to Korean Won

I want the amount of the foreign currencies in row "R" to be shown in the "Q" row.

However, the formula below gives me just a zero.

IF(R2="[\€]\d+",GoogleFinance("CURRENCY:EURKRW")))*R2

Korean Won in row Q and foreign currencies in row R:
