[Q] GScript error while creating a back up of my ROM

Hi there, im using a samsung galaxy s3 clone and iv encountered a few issues that im unable to resolve on my own while following the instructions on this post.
http://forum.xda-developers.com/show....php?t=1825722

1. I followed the steps to root with DooMLoRD_v4_ROOT but after completing the process and rebooting, there is not super user icon.
But i managed to find a another root with super user acess ( Root_with_Restore_by_Bin4ry_v18 )

2. When attempted to run the back23 script from Gscript, I get the following error messages. Screen Shots below.

Look forward for your help.
