Here's the situation:

I have a sidebar in a mobile theme that I only want to show on the front page. My knowledge of PHP is a little fuzzy here. I thought I could combine the conditional statement with the existing sidebar code like so:
```
<?php if (is_front_page() && !function_exists('dynamic_sidebar')
|| !dynamic_sidebar('home-video-link') ) : ?>
<?php endif; ?>
```
But it doesn't work. What am I doing wrong? I just took what was there and added the is_front_page() && to the front of. Is that wrong?

Thanks for any assistance!

If I had to guess, I'd say it's a problem with your Boolean logic syntax.

Change this:
```
if (is_front_page() && !function_exists('dynamic_sidebar')
|| !dynamic_sidebar('home-video-link') )
```
...to this:
```
if ( is_front_page() && ( ! function_exists( 'dynamic_sidebar' )
|| ! dynamic_sidebar( 'home-video-link' ) ) )
```
Alternately, get rid of the ! function_exists( 'dynamic_sidebar' ) altogether. The dynamic_sidebar() function was defined in about version 2.8 of WordPress, so backward-compatibility is no longer necessary. So, you could simplify it as:
```
if ( is_front_page() && ! dynamic_sidebar( 'home-video-link' ) )
```

Brilliant, thanks so much! That did the trick. I'll look up that dynamic sidebar function too, so I have a better understanding of it. Many thanks.
