That is somewhat strange. I am not exactly sure how you are running the
script because sometimes the J environment might run a script within an
explicit verb without one being necessarily aware of it and some scripts
(such as the Wicket Toolkit) can be affected.
Try the following:
open a new editing window in JQt and type,
u@:v
then Run/All Lines (Ctrl+Shift+E) and you should get an error,
u@:v
|value error: scriptd
| u@: v
| ...
because the system is (probably) running the script within an explicit verb.
Now try the following instead:
Ctrl+A followed by Ctrl+E (with focus on the editing window), you should
get no errors,
u@:v
u@:v
just as if you had typed the line on the execution window.
I had no problems running the following script, using Ctrl+A followed by
Ctrl+E (with focus on the editing window), on a fresh installation of J807
(beware of line-wrapping),
JVERSION

test=. u@:(1 + u) Adv

clear'' NB. I know, I know
RunWT''

This is the session output,

Moreover, I ran the script many times (using Ctrl+A followed by Ctrl+E
repeatedly) without any issues. You might consider modifying the script,
according to the path where your updated Wicked Script is, and try to run
it exactly as is described above.
I hope it helps
