$_SESSION['currentbid'] isn't available until you do session_start();
session_start();
unset($_SESSION['currentbid']);
Or is this what does connect.inc contains?

I more or less figured that. below is the code for the two pages in question.
Page 1:
<?
require("connect.inc");
unset ($_SESSION['currentbid']);
?>
<HEAD>
<TITLE></TITLE>
</HEAD>
<BODY>
Borrowers
<TABLE BORDER="1">
<TR>
<?
/* Get all users select call */
$users = mysql_query("SELECT bname, bphone, address, admin, bid FROM Borrowers
ORDER BY bname");
echo "<TH>"; echo "Name"; echo "</TH>";
echo "<TH>"; echo "Phone"; echo "</TH>";
echo "<TH>"; echo "Address"; echo "</TH>";
echo "<TH>"; echo "Admin"; echo "</TH>";
echo "<TR>";
if($users)
while($row=mysql_fetch_row($users))
{
echo "<TR>";
echo "<TD> $row[0] </TD>";
echo "<TD> $row[1] </TD>";
echo "<TD> $row[2] </TD>";
if($row[3])
echo "<TD> Yes </TD>";
else
echo "<TD> No </TD>";
print "<TD> <FORM METHOD=\"post\" action=\"uupdate.php\">
<input type=\"hidden\" name=\"ubid\" value=\"$row[4]\">
<INPUT TYPE=\"SUBMIT\" VALUE=\"Change User.\">
</FORM> </TD>";
print "<TD> <FORM METHOD=\"post\" action=\"udelete.php\">
<input type=\"hidden\" name=\"ubid\" value=\"$row[4]\">
<INPUT TYPE=\"SUBMIT\" VALUE=\"Delete User.\">
</FORM> </TD>";
print "<TD> <FORM METHOD=\"post\" action=\"uadmin.php\">
<input type=\"hidden\" name=\"ubid\" value=\"$row[4]\">
<INPUT TYPE=\"SUBMIT\" VALUE=\"Make Admin.\">
</FORM> </TD>";
echo "</TR>\n";
}
?>
</TR>
</TABLE>
<? require("tail.inc") ?>
page2:
<?
require("connect.inc");
?>
<HEAD>
<TITLE> User Update Page </TITLE>
</HEAD>
<BODY>
<BR>
<BR>
<?
print "$currentbid-current, $ubid-change, $bid-current";
?>
<?
if($admin)
$currentbid = $ubid;
else
$currentbid = $bid;
$result = mysql_query("SELECT bname, bphone, address FROM Borrowers Where
bid=$currentbid");
if($result)
{
$row = mysql_fetch_row($result);
$oname = $row[0];
$ophone = $row[1];
$oaddress = $row[2];
}
?>
Please enter the new information into the fields below.
<TABLE BORDER>
<TR><TH> Current Information </TH></TR>
<TR><TH><FORM method="post" action="ucupdate.php">
<INPUT TYPE="text" NAME="uname" value=<?print "'$oname'"?> SIZE="30"></TH>
<TH><INPUT TYPE="text" NAME="uphone" value=<?print "$ophone"?> SIZE="30"></TH>
<TH><INPUT TYPE="text" NAME="uaddress" value=<?print "'$oaddress'"?>
SIZE="30"></TH></TR>
<?
if($admin)
{
print "<TH><INPUT TYPE=\"text\" NAME=\"upassword\" value=";
$cpass = mysql_query("SELECT admin_pass FROM Borrowers WHERE bid=$currentbid");
$cpassr = mysql_fetch_row($cpass);
print "\"$cpassr[0]\" ";
print "SIZE=\"30\"></TH></TR>";
}
?>
</TABLE>
<INPUT TYPE="SUBMIT" VALUE="Submit your information.">
<INPUT TYPE="RESET" VALUE="Clear">
</FORM>
<? require("tail.inc"); ?>
The first page gives the admin user a list of users, and three options (change their
information, delete them, or make them and Admin). The option we are choosing is to
change information. If I select user number 1 the only way to edit another user is to
log out and log back in.
If any of the code is unclear please let me know. I haven't gotten to commenting it
all yet.

Subject: Re: [PHP] UNSETing Session Variables
I tried to enter the comand as such
unset ($_SESSION["choice"]);
I thought everything in php was double quotes. but even with single quotes it still
isn't quite working. If I do it on the first page then it won't let a later command
assign anything to the variable, but if I do it on a seperate third page, it doesn't
reset anything.
I have been trying to avoid unregistering variables and then reseting them. Seems
a little too messy for my programming tastes.

unsset($_SESSION['choice']);
// .. or .. //
session_unregister('choice');
