Oops! Operator Error!

As I have said before, this single two tie I am working on requires me to throw the shuttle in a certain way, or rather a certain order. If I don't, then an error shows up. I should be weaving:

tie down 1 plus pattern shaft 5

tabby a

tie down 2 plus pattern shaft 5

tabby b

tie down 2 plus pattern shaft 5

tabby a

tie down 1 plus pattern shaft 5

tabby b

I think I used the tied down order 1-2-2-2 to cause the error!!

Do you see the error?

error!!!

 Do you see where I have fixed it?

corrected
