Here, I will show you how you can change the location of currency selector in Magento.

By default, the currency selector is displayed in the left sidebar. Here, I will show you how you can show it in right sidebar.

Showing currency selector in product view detail page

Put the following code in layout/directory.xml

<!--
Product default layout
-->

<catalog_product_view>
	<reference name="right">
		<block type="directory/currency" name="currency" before="-" template="directory/currency.phtml"/>
	</reference>
</catalog_product_view>

Showing currency selector in homepage

Go to Admin Panel -> CMS -> Manage Pages -> Edit Homepage

Click Custom Design tab in left sidebar

Write the following code in Layout Update XML box.

<reference name="right">
	<block type="directory/currency" name="currency" before="-" template="directory/currency.phtml"/>
</reference>

Hope this helps. Thanks.
