show_count example

Hi
Been testing this out today and seems good to me. I do have an issue trying to show the number of posts in each category. Your docs say to use show_count either 1 (to show) or 0. But it doesnt say where to put this. I tried :
[searchandfilter fields=”search,category,post_date” types=”,,daterange” headings=”, ,From / To” show_count=”1″ submit_label=”Search”]

for example but nothing happens. Im not sure where else to try. An example in the docs for options like this would be great please.
