Help with Advanced Search

I’m using the responsive auction theme and by posting this in the general forum, was hoping someone could help me with ADVANCED SEARCH.

I’ve spent a lot of time customising my site (www.mygolftrader.eu), including ages getting Paypal Split Payments but I am now baffled with advanced search.

I’ve added in some of the custom fields I’d set up but still get search results that are at best ‘patchy’ and I have no confidence in them. Quite often I get a ‘ZERO’ results when i know I am searching for something that is there.

It really should not be this difficult to set them up – I’ve now lost count how many times I’ve gone through the video and I’ve checked that they follow the same procedure.

I just can’t fathom wher I am going wrong.

Its now really bugging me!! Any help/guidance gratefully received.
