Help please!!! Custom feed error "….is not a valid feed template."

My objective is to create custom feed. I added the following code to the themes’ function file.

But the url http://example.com/?feed=info returns the error ERROR: info is not a valid feed template.

It looks like this method has worked for many. Please help me to find what is wrong with this code.

Code used in functions.php file:

add_feed('info','myFeed');

function myFeed() {
