question about $_GET

Copy linkTweet thisAlerts:
Jul 20.2006

Say I have a url that looks like this:

firmancomputers.com/display.php?Link_Num=9&action=5

but sometimes the url only looks like this:

firmancomputers.com/display.php?action=5

In a PHP program.. How can I do something like:

[B]if ($_GET[‘Link_Num’] == “”) {[/B]

It does not like the code I put. Any input would be great.
