The dialogs for Script-fus are generated and handled by the GIMP.
Unlike plug-ins and other scripting languages, there is nothing that a
Script-fu script has to do to interact with the user -- the parameters
are defined by the dialogs before the 'script-fu-*' function is
evaluated. This is why the function is considered non-interactive.

Sort of. You have a couple of unwanted parentheses in your 'set!'
statement and 'drawable' is being treated as a function. The
appropriate syntax would be:
(set! drawable (car (gimp-image-get-active-layer image)))
You're doing well for only your second day with Scheme. One thing that
might help you in debugging scripts is using the Script-fu console. If
you open the console ("Xtns->Script-fu->Script-fu Console") and
execute your command providing appropriate parameters:
then the error messages produced will be somewhat more useful than
"experienced an execution error".
