display function not working

[libinaz]

My display function doesn't work. It works if it's called up on its own, without the other if/else, but doesn't work through the display function. It doesn't seem to get the value of $institutionname. Is there something I need to post/do for it to get that variable?

<?php
function display_contact_form()
{

<?php $query_billemailw = "SELECT * FROM users_tbl WHERE institutionname =
'$institutionname' AND expired < 3 ORDER BY bill_email ASC";
$billEmailw = mysql_query($query_billemailw) or die(mysql_error());
$row_member4 = mysql_fetch_assoc($billEmailw);
?>

Where it is called up from
[code]
<?php
$query_contact = "SELECT * FROM users_tbl WHERE bill_email = '$billEmail'";
$institutioncontact = mysql_query($query_contact) or die("Problem with the query: $query_contact<br>" . mysql_error());
$row2 = mysql_fetch_assoc($institutioncontact);
if (isset($row2['institutioncontact']) && $row2['institutioncontact']=="Yes") {
display_contact_form();
}
else
{
$query_wwcontact = "SELECT * FROM users_tbl WHERE institutioncontact = 'Yes' AND institutionname = '$institutionname'";
$institutionwwcontact = mysql_query($query_wwcontact) or die("Problem with the query: $query_contact<br>" . mysql_error());
$wwrow = mysql_fetch_assoc($institutionwwcontact);
if (isset($wwrow['institutioncontact']) && $wwrow['institutioncontact']=="Yes") {
echo 'Your institution contact is ' . $wwrow['lname']; echo', ' . $wwrow['fname']; echo', ' . $wwrow['bill_email'];

I can't find where the variable in question is ever being set to a value. Where are you intending to get the value for $institutionname?
