bitrate object...is this correct?

I have several films that are not ABR.  I want to make sure I have this coded correctly. On one of the lines in json for a film it shows it's okay. When I add this same code to another film in the same json it gives me a red X by the line item so I can't seem to find out why.. 

I am suppose to have quotes around the integer, right?

"videos": [{
					"url": "http://xxxxx_512kb.mp4",
					"quality": "HD",
					"videoType": "mp4",
					"bitRate": "600"
