php5 - ReadFile, Make Page then POST

I am trying to make a php/sql page that reads a text file that has a header row, then displays the rows and allows the user to select what type of information each row contains. For some reason I cannot get the POST method to work on the select boxes that I generate. Let me know if there is a easier way to write this or if there is something that I have done wrong.

fileRead.php
//all this **** works as far as opening a file
$filename = "path.txt";
$fd = fopen($filename, "r");
$contents = fread($fd, filesize($filename));
$delimiter = "\n";
$splitcontents = explode($delimiter, $contents);
$headerRow = explode("\t", $splitcontents[0]);
$x = 0;

$con = mysql_connect("localhost","user","password");
mysql_select_db("contact", $con);

//This will work
echo "<table border='0'><form method='post' action='fileInsert.php'>
<select name='test'><option>ABC</option><option>123</option>";
echo $headerRow[$x];

//This will not work
while($headerRow[$x] != ""){
$row = $headerRow[$x];
echo "<table border='0'><td>".$row."</td><td>
<select name=".$row.">";

$fields = mysql_query("SELECT * FROM fields", $con);
echo "<option></option>";
while($row = mysql_fetch_array($fields)){
echo "<option>".$row[fieldTypes]."</option>";
}
echo "</td></table>";
$x++;
}
echo "<td><input type='submit' name='submit' value='Insert'></td></form></table>";

So this part works perfectly as far as populating the select boxes and showing the names of the header rows.

Employee Number [SELECT BOX]
Full Name [SELECT BOX]
Date Of Birth [SELECT BOX]
Date Of Hire [SELECT BOX]
Grade [SELECT BOX]
[SUBMIT]

My problem is, when I hit submit. The top select works and displays ABC and Grade but if there is a space in it it wont work, Employee Number in this case. Is there any way to remidy this?? A easier way to do the whole thing??

<?php
echo $_POST["test"];
echo $_POST['Employee Number'];
echo $_POST['Grade'];
?>

Try double quotes

echo $_POST["Employee Number"];

Both single and double quotes are valid so that should not be the issue. I think some more info is needed to answer this one... for instance the structure and contents of the txt file and db.
