Thank you for your help. Sorry for the slow reply I have been travelling.
Perhaps you can help with a final layout/presentation issue.
The Search works but the filters I would like to show only appear after you have entered some text.
In my mind the idea was that the Filters would be at the top of all search pages where you can select the brand and multiple or individual types of produc from the check boxes.
or
simply type BMW for example into the search box.
I don’t seem to be able to make this function.
