Retrieve Jwplayer Video Player Files From The Database?

i am trying to load video to jwplayer you can do it from by putting the name of the files directly into the script like this

Code:
<a href="#" onClick="jwplayer().load({'file': 'video_SD.mp4', 'hd.file': 'video_HD.mp4'})">

but now i want the names to come from the database so i tried it like this

Code:
echo "<td><a href="#" onClick="jwplayer().load('file':" . $row['first_vidoe'] . "'file.hd':" . $row['2ndvideo_HD'] . "' )">" . $row['FirstName'] . "<a/></td>"; echo "<td>" . $row['Age'] . "</td>";
