HI,
I am not sure about the error. I modified the script and added 12 (hopefully
all the locations) and didn't had any problems.

Dear Arun,
I checked the command and did some addition to make them purposeful. I didnt
change any, except adding 12 at specific location.

When i use your commands, i dont get this error.
