I am trying to retrieve data field from a database and store them in a dropdown box so that they correlate to each other which i have done but when I put them into a dropdown box they appear but with no spaces between them and I want the words separated. Any help much appreciated.

Select from the list below<br>
<select name="Film" t[enter link description here][1]itle="Select DVD">
    <option value="" selected disabled>Select DVD</option>
<?php

$result = mysqli_query($con, "SELECT `DVD ID`, `Title`, `Certificate` FROM tbldvd;");
while ($row = mysqli_fetch_assoc($result)) {
    echo "<option value='" . $row['DVD ID'] . $row['Title'] . $row['Certificate'] . "'>" . $row['DVD ID'] . $row['Title'] . $row['Certificate'] . "</option>";

}
?>
</select><br>
<a href="menu.php"</a>Return To Main Menu<br>
<input type="submit" name="Submit" value="Select DVD">
</a>
</form>
