Need help for filter post with Oxygen repeater and Metabox Custom Field

Hi, I'm not good for php and wp_query. I try to learn and setting for a few day but still fail. So I need your help now...

I make a job application by using custom post type and custom field. I have a custom field name "status". This "status" field have 2 option :
1. open
2. fulfilled

My objective is to use Repeater to show the post that have "open" status.

I try to use Advance Query in Oxygen but I stuck how to setup the "open" status filter.

Please guide me.

Thanks,
