How can i display the price in the RSSFeed?

I already tried the following but none of them worked:
echo '<price><![CDATA[', $item['i_price'], ']]></price>', PHP_EOL;
echo '<price><![CDATA[', $item['price'], ']]></price>', PHP_EOL;

echo '<price>', $item['i_price'], '</price>', PHP_EOL;
echo '<price>', $item['price'], '</price>', PHP_EOL;

Use osc_format_price function.

Thank you,

However, I am really sorry and don't know how and where to integrate this; could you help me?

The best i could do was to showcase everywhere 'Check with seller'...

However there are prices (numbers and different currencies filled in.

Input: echo '<price>', osc_format_price($item['price']), '</price>', PHP_EOL;

Gives us >

Output: <price>Check with seller</price>

Means $item['price'] is NULL.

okay, but real quick, how wold i solve this?

You do not have correct array key

okay thank you, can this be solved easily? if yes can you help me please.
