Thank you very much. This is exactly what I needed to know in order to implement this. I'll now get to the coding and let you know how it turns out. Thank you again. You have been very helpful and patient.

Oh. I just noticed 1 thing with your URL. You didn't put two trailing ' before the final ;. 1 for the 'http statement and 1 for the ' + categories.value statement. Is that intentional? Or should it be written "'http.....;"?
