Variables passed from menu

[habs20]

I have a drop down menu where a user can select to pull up documents by their doc date. Dates are code as 1qtr 2qtr 3 qtr & 4qtr. Each document is tagged in via a date filed in a file table. Selecting the files based on date works, problem happends when I try to sort my results. By default the page displays 1qtr dated documents. When I sort 4qtr documents it reverts back to 1qtr docs.

Here is the code I am using on my page:

if($GET['jumpMenu']=="1")
$date = '1qtr';
elseif($GET['jumpMenu']=="2")
$date = '2qtr';
elseif($GET['jumpMenu']=="3")
$date = '3qtr';
elseif($GET['jumpMenu']=="4")
$date = '4qtr';

if (!isset ($GET['date'])) {
$date = '1qtr';
} else {
$date = $GET['date'];
}

How do I get the date to stay the same as what what selected after I sort the columns?

Thanks for any help and suggestions.

Try adding the curlies to keep your ifs seperated.
I also rewrote the code to simplify it.

$default = "1qtr";
if (isset($_GET['jumpMenu'])) {
    if($_GET['jumpMenu'] == 1) { $date = '1qtr'; }
    elseif($_GET['jumpMenu'] == 2) { $date = '2qtr'; }
    elseif($_GET['jumpMenu'] == 3) { $date = '3qtr'; }
    elseif($_GET['jumpMenu'] == 4) { $date = '4qtr'; }
    else { $date = $default; }
} else {
    $date = $default;
}
