Blank content for description in head code

I've just had quick try at making meta description, in head code, same as description for album or photo being viewed.
Editing themes/default/views/page.html.php

Blank so far.

Looking at a bit of other code, such as for the <title> tag, I've tried:

<meta name="description" content="<?= $description ?>" />
and
<meta name="description" content="<?= $item>description ?>" />

- but content just blank.

At least, though, I didn't stop my site working, as I've done at times when messing w php code!

Thanks for the thread link; code there works

Dave had suggested would be a simple change to the file; to me, I think nigh on impossible to figure just what to do!
