Test 8

You should see "blah", what you typed, then nothing for the "notused" variable.
thehidden is:
<%=[ns_queryget "thehidden"] %>

What you typed (atext) is:
<%=[ns_queryget "atext"] %>

notused is (should be blank):
<%=[ns_queryget "notused"] %>

(Check your server log for the query set.) <% ns_set print [ns_conn form $conn] %>
