i am working in a autorig, just creating a basic leg, and some fingers controls,
if i select all my script, and run it, it has some errors, and sometimes doesn’t find objects in the scene. 
but if i grab a bunch of lines run them, and then another bunch and run it, everything runs fine.

does MEL take in account empty lines? or is something special i need to do to make it work?
Thanks =)

if i run paragraph by paragraph it runs fine, but if i copy all of it and execute all at once i get the error
// Error: No object matches name: pointConstraint //
// Error: No object(s) to duplicate //

at the end of it.
