 "deciding" is not enough.  this is software engineering.  you cannot
just "decide".  as in *you* cannot just "decide".  you have to get the
*machine* to print out the values [or use a kernel-level debugger to
find out].

 you've been given standard software engineering debugging advice.
this standard software engineering debugging advice you will get no
matter _where_ you ask the question.

  follow the advice that i've given you else there is no further
assistance that i nor anyone else can give you.
