Update Solved problem!

After examining the code, the freaking problem was I was missing the }else{} after

header ('location:referraldone.php?say=blankfields');
}

I'm really lost at the moment with this session code. I don't understand why the session isn't working. Where did I go wrong? I'm trying to take the data entered in the fields to the next page when someone makes an error not filling an required field. Codes are below:

<?php

if (!$_POST['cname'] | !$_POST['cphone'] | !$_POST['caddress'] | !$_POST['ccity'] | !$_POST['cstate'] | !$_POST['czip'] | !$_POST['cbirthday']) {

$rname = $_REQUEST['rname'];
$rdate = $_REQUEST['rdate'];
$ragency = $_REQUEST['ragency'];
$rphone = $_REQUEST['rphone'];
$cname = $_REQUEST['cname'];
$cphone = $_REQUEST['cphone'];
$caddress = $_REQUEST['caddress'];
$ccity = $_REQUEST['ccity'];
$cstate = $_REQUEST['cstate'];
$czip = $_REQUEST['czip'];
$cbirthday = $_REQUEST['cbirthday'];
$medmemid = $_REQUEST['medmemid'];
$medclaim = $_REQUEST['medclaim'];
$marital = $_REQUEST['marital'];
$income = $_REQUEST['income'];
$gender = $_REQUEST['gender'];
$race = $_REQUEST['race'];
$caregiver = $_REQUEST['caregiver'];
$relationship = $_REQUEST['relationship'];
$memphone = $_REQUEST['memphone'];
$physician = $_REQUEST['physician'];
$phyphone = $_REQUEST['phyphone'];

session_start();
$_SESSION['rname'] = $rname;
$_SESSION['rdate'] = $rdate;
$_SESSION['ragency'] = $ragency;
$_SESSION['rphone'] = $rphone;
$_SESSION['cname'] = $cname;
$_SESSION['cphone'] = $cphone;
$_SESSION['caddress'] = $caddress;
$_SESSION['ccity'] = $ccity;
$_SESSION['cstate'] = $cstate;
$_SESSION['czip'] = $czip;
$_SESSION['cbirthday'] = $cbirthday;
$_SESSION['medmemid'] = $medmemid;
$_SESSION['medclaim'] = $medclaim;
$_SESSION['marital'] = $marital;
$_SESSION['income'] = $income;
$_SESSION['gender'] = $gender;
$_SESSION['race'] = $race;
$_SESSION['caregiver'] = $caregiver;
$_SESSION['relationship'] = $relationship;
$_SESSION['memphone'] = $memphone;
$_SESSION['physician'] = $physician;
$_SESSION['phyphone'] = $phyphone;

A few obvious problems with your code:

Your are using binary OR | instead of the boolean or || in your if clause.
Instead of manually localizing the variables, you might as well extract($_REQUEST); - This is probably bad advise, since you might not understand the security implications of your script running entirely in the global scope.
So the (better) alternative would be to manually foreach ($_REQUEST as $key=>$value) and thus fill up your $_SESSION. Do so likewise in the second script.
Remember: Foreach loops are our friends.
Likewise the html output can be accomplished in a loop, reducing the overall code size.
You might be missing a session_start, or also likely: have premature output and got a notice which you didn't tell us about.

session_start must be called before you read from -or write to- the $_SESSION variable. In the second page "error page", you placed session_start but after you tried to read the $_SESSION var, so place it in the top of that "error page" instead of the middle.

Okay, some rewriting help.

I would ultimately start by making a descriptive array of the field names and titles. This way you have a secure list of acceptable input fields and simplify the output later on.

$allowed_fields = array("
      "cname" => "* Client name",  // titles may include <b>HTML</b>
      "phone" => "PHone number",
      "caddress" => "Address",
      ...
");

But to simplify the first script, you can replace the 50 lines of $_REQUEST input and $_SESSION filling with just:

session_start();
foreach ($_REQUEST as $field=>$value) {
    $_SESSION[$field] = $_REQUEST[$field];
}

And all the form field output can be simplified this way:

foreach ($allowed_fields as $field=>$title) {
    ?><tr>
    <td valign="top"><?=$title?>:<br /><input name="<?=$field?>" type="text" value="<?=htmlspecialchars($_SESSION[$field])?>" style="width:98%" /></td>
    </tr><?php
}

additional to the things that has already been talked about: You'll need to put the session-ID into the URL you redirect to, to have it present if cookies cannot be used.

header ('location:referraldone.php?say=blankfields&'.SID);

This will not be done automatic, even not when you use session.use_trans_sid
