Thanks Jarvis, I appreciate that you took the time to reply in detail. This is very interesting. I think I could learn a lot studying your code. Yesterday I moved on to trying a plugin (Search & Filter Pro) which also uses Ajax. I’m having some issues with it (it works fine on my local site but so far no luck on the live) so I may be back to trying to do it on my own if I can’t find a resolution. For now I’ll leave this open just in case…
