What does the error mean "??? Undefined function or method 'makeLeveledHierarchy' for input arguments of type 'double'".

I have checked the directory, I have placed the script in the current directory. Any suggestions on how to fix the problem, would of great help. Thank you

Your code might be cd'ing to a different directory before it tries to execute that function. Or you might have a spelling mistake.
