ok.. working on the book filters isn't too bad once you locate the book files that do it.. the awkard thing is, for a multiple product search result page the zencart code does one thing, and for a single product search result it does another.
There is a url redirect line in the zencart code that does one of the 'return results' pages, in testing one needs to comment that out and then use php echo's to make whatever output you choose, appear. But, if you put a php echo in the code before the activated php redirect line, the redirect itself doesn't work. It can be frustrating..
If you have specific probs in code areas do p.m me rather than fill up the thread with deep technicals :)
