Cannot get trailer to display with production

I have uploaded a trailer which is 30 seconds, file size is 7.12 MB and it is an MP4. I've filled out the necessary data in Scorecard and submitted the video. I cannot see the trailer associated with my production anywhere. Our station is part of the PBS system and I would like the trailer to play in a manner similar to "Frontline" or "NOVA". If anyone knows what I am doing wrong please let me know. I have a lot of content that needs uploading and my management wants to see the trailer. Thank you.
