lookup isn't working

Hi Paul,
Lookup feature on the far right corner isn't working for me.

This is what I did, I clicked lookup and chose reference ID in the drop down menu. Tried to type a reference ID in the next search box, even before I go to next digit, it says cannot search field reference ID.

I am using 7.22 pro.
