Sets stopped working

Hi

The first set on my gallery page works but the rest have stopped??

I swopped the set id from one of the ones not working to see if it was an id error but it’s not – if it’s the first set on the page it works fine but any after that don’t work??

Please fix this error as I have several sets on my gallery page.

Thanks

Rob
