You need to give the full error, which includes the line at which the
error occurred, and the backtrace. Then show what line that line number
corresponds to.

You’ve posted a large amount of code, but for me it’s not even runnable

  • the first line calls a method “file_loaded?” which on my system (ruby
    1.8.7) doesn’t exist.

So if you cannot boil this down to a five-line standalone test program,
then you must at least show the exact error and context.

Also, what ruby type and version are you using, and on what platform?

Thanks for your reply. Fortunately I somehow managed to debug the error.
The sad part was there was no mention of the line in which error
occured! All that was posted is "

Error Loading File slab.rb
undefined method `*’ for nil:NilClass"
I am using Ruby 1.8.6 on Windows 7 (64 bit)by the way…
