Thanks everyone, I now have two working controls on my interactive graph.
The direct assignment to my parameters from the id did it (along with some
punctuation corrections)
I noticed that when I manually enter the set bparm in the GRAPH script, that
it disappears from the script when I close the Design window. What am I
doing wrong?
I thought that the pas command put a border around the isigraph but it
doesn't seem to. Can I add one? I would ultimately like to add axis tick
marks but I don't know if this is possible.
Finally, is there any way to change the 0, 0 origin to be at the bottom left
rather than top left?
Again, thanks all for getting me this far.
Bob

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.
