NOTICE is not a real error. It is just a warning that you are using an undefined index in an array somewhere. I would just turn off notices in my php.ini file (set error reporting to all except notices, as someone posted before). You do not need to change your code.

Explains it better than i would. (apart from saying that you do not need to modify php.ini to turn off notices, it an be done using error_reporting(E_ALL ^ E_NOTICE); as you may not be able to edit php.ini)

Just an example of the wonders of Google for you

Ya, PHP is simply telling you that the variable does not exist in the array (like matthewJ said). In other words, it couldn't find 'page' in the query string.
Notices are nothing to be concerned about unless you are 100% for the E_ALL complience, which I personally see no need for unless you believe PHP will make it mandatory later on or something. PHP is quite lenient, and I use that to my advantage alot, lol.

thanks guys, thats great!

if i dont actually solve the problem (the notice thing) does it leave my site unsecure or anything?

[Demonslay]

In most cases, no.
The only reason I would think of that is if you were using a very sensitive variable to grab from or something that didn't exist and could crash the script if that variable was not set correctly. Thus why you always need to throughly parse and make sure incoming data is what it should be.
I honestly don't know alot of the notices that PHP issues, since I always have error_reporting in my ini directive to ignore them, lol.
