Drupal 7.x

Hi. First Post on drupal.org.

Ok, so I wanted to change the header image based on path or prefereably content type. But ok.
So I found this great post - http://drupal.org/node/104601#comment-1071795. Some really older posts there.

I tried some scripts in my page.tpl.php and found one that seemed to work well and do what i wanted.
I have since realised that it is giving errors after thinking it worked perfectly. This is based on the busy theme.

Here are the errors:
•Notice: Undefined variable: node in include() (line 34 of /home/forefron/public_html/sites/all/themes/busy/templates/page.tpl.php).
•Notice: Trying to get property of non-object in include() (line 34 of /home/forefron/public_html/sites/all/themes/busy/templates/page.tpl.php).
•Notice: Undefined variable: node in include() (line 36 of /home/forefron/public_html/sites/all/themes/busy/templates/page.tpl.php).
•Notice: Trying to get property of non-object in include() (line 36 of /home/forefron/public_html/sites/all/themes/busy/templates/page.tpl.php).

Hi!
I use Aggregator module to import rss feeds to my page. Everything works all right. The question is: can I use the field that comes in the rss xml? I need to categorize the feeds using that field and I don't know how to do it. Maybe I'm missing something in that module..
Please anyone could help me?
Cheers!

Hello.

I am brand new to Drupal. I installed 7.4 and have it working. So far I love the software. Everything is quite sensible. I have one challenge and am hoping someone can point me in the right direction.
