wd'q' should never be used (except for the use in wdhandler). wd'qd' is also
very rarely required. In an event wd'qd' just returns all the info that
wdhandler has already set for you. The only use of wd'qd' would be to get
info from a form other than the one with the event. And even there it would
generally be better to have that info collected and saved in events on that
form.

Just as Eric said, aparm has already set for you by wdhandler. And because
wd'q' for that event has already been consumed by wdhandler. When you call
wd'q' again and because there is no pending event therefore it raise an
error. However if you are interested in what the event data were, you may
still get it by wd'qd', eg.
graph_aparm_button =: 3 : 0
1!:2&2 wd'qd'
a=. ". aparm NB. aparm is a string
wd 'set values *','A = ',": a+0.25
....
