Assigning GET var to regular var.

[DaveRich]

I am having a strange issue that I think may be a syntax problem but I dont understand completely.

Here is my code:

    if(isset($_GET['famType']))
    {
        $famTypeStr = $famTypes[$_GET['famType']];
        echo "<script>alert('famType: " . $_GET['famType'] . " | " . $famTypeStr . "')</script>"; //DEBUG
    }

    if(isset($_GET['geo']))
    {
        $subgeoStr = $_GET['geo'];
        echo "<script>alert('geo: " . $_GET['geo'] . " | " . $famTypeStr . "')</script>";    //DEBUG
    } 

I am requesting the page containing the above code passing the get parameters as follows: ../page.php?famType="M01"&geo="2"

The alert box pops up for both if statements and it prints the contents of the get variables as desired, but both $famTypeStr and $subgeoStr are null.

Is there something wrong with the assignment syntax I'm using in these cases?
