Relationship not working under Custom Fields extension in {exp:weblog:entries /} ?

I am just trying this extension for my old EE 1.5 site. After checking out this thread a bit, it works fine now. IT’s GREAT.

But I discovered that when I change a field in the weblog to a “RELATIONSHIP” field, it returns no records. I am sure that I only change a field to “RELATIONSHIP” before that it’s working and returning what I want.

Can anyone help ? Or how can I deal with a relationship field where I want to display a value according to the current weblog field ?
