Not getting option value from my database...

Hello,

I am trying to get an option value from a database.  I'm using the  
following code snippet.  This is a postgres 8.3.6 database.  I am able  
to use echo to get a list from the database.  The code appears to  
work, but later when I try to echo the id from the selected record, I  
get no result.  What I'm trying to do, is select the appropriate row  
from the database using the options menu construct.

                   <form method="POST">
<?
   echo "<p> Choose your prospect:<br /><select name='GetName'  
size='". $rows ."'>";


               while (list($peopleId, $fName, $mName, $lName,  
$contactItem) = pg_fetch_row($SciName))
                  {
                  echo "<option value='".$peopleId."'> ". $fName .  "  
" . $mName . " " .$lName . "&nbsp;" . " ---". "&nbsp;" .  
$contactItem . "</option>";
                  }
               echo "</select>";
?>
			<br />
			<br />
  			<input type="submit" name="get_name" value="Submit" />
            <input type="reset" value="Reset" /></p>
            </form>

<?

    }

           }
if ($get_name == "Submit") { echo "People Id = " . $peopleId. "<br / 
 >";  }

Thank you for your time,

Carol Walter
