Hi,

Python interpreter goes through the script file line by line and also
execute the lines one after another. When it is finished with line 15 it
goes and interpret line 16.. In your case, when you call O.step() for the
first time, the interpreter (as the error says) does not have any idea what
checkUnbalanced is (because the definition has not been done yet).

Just put O.step() at the end of the file and it should work :-)

cheers
Jan
