help constructing if else statement

[adammc]

Hi,

I am having problems getting this statement to work correctly:

[PHP]<?

// find out if logged in as a buyer or seller
//otherwise show a page to ask them to register or login first

if (isset($_SESSION['first_name'])) {
echo "<a href=\"buyers/members.php\">";
}

if (isset($_SESSION['sellers_first_name'])) {
echo "<a href=\"sellers/members.php\">";
}

else {

echo "<a href=\"need to login.php\">";

}
?>[/PHP]

I am gettiing the right link show if logged logged in as a seller (sellers_first_name) but Im getting the 'need to login' link when logged in as a buyer ?

[smatts9]

<?
if(isset($_SESSION['first_name'])) {
echo "<a href=\"buyers/members.php\">";
} elseif(isset($_SESSION['sellers_first_name'])) {
echo "<a href=\"sellers/members.php\">";
} else {
echo "<a href=\"need to login.php\">";
}
?>

I hope that works for ya.
