problem validating feed

i am a total newbie, so please pardon this simple question. my feed validates but i get this message:

This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.

*

line 10, column 8: title should not be blank [help]

<title></title>
^

where do i find this code to fix it?

thanks in advance for helping the new kid.
