work with repeater on my site header

I’m trying to use a repeater that connect to database on my header. And it just doesn’t work
I put in the database some filter but that’s not what keeps him from working.
when i put the repeater on any page, not on my header, it’s work perfectly.

What am I doing wrong?
What code should I put on my Site Code?

Please help!
Thanks!

It should work even without code. Try to explain what exactly doesn’t work.

Hello Amir,

I replied to your (same) question in the Totally Codable FB group. Just in case I will reiterate here:

Make sure to attach any associated dataset to the header. Make sure it attaches correctly. It is best to add a new dataset, configure it, then make the connections to the repeater once again.
