Hi Jason
That's perfect, thank you so much for your swift and continued assistance.
Just one final question if that's okay - is there anyway that when this page first loads that all of the checkboxes are checked so that all products are listed initially? The visitor would then simply deselect the options they don't want - from a marketing point of view it will help as all of their products will be visible to see at least once.
I did try simply adding..... checked="checked" ...... into each option, but obviously when the pages reloads they all appear checked again. I have worked a way around it by having a duplicate of the page with the above code added to all the options, then when SUBMIT is first hit it goes to the combined Search/Results page you've been helping me with which is then used from then on. The only downside with this is that since I'm running two very similar pages, any changes would have to be applied to both as opposed to just one.
It's not a deal breaker but would be the icing on the cake if I could just retain the one page.
Many thanks again.
Kind regards
Paul
