A question about "split"

[susi]

Thank you Patryk_F

• When I find "2"(index2), "5"(index2), "8"(index1) in "123456789"
  It works → 67
• When I find "2"(index2), "0"(index2), "8"(index1) in "123456789"
  It works → ERROR IN BLOCK 0, NO INDEX 2
• But when I find "2"(index2), "5"(index2), "0"(index1) in "123456789"
  It shows → 6789
  It don't know "8" has been changed

When index 1, there is still a little problem

• When I find "2"(after), "5"(after), "8"(before) in "123456789"
  It works → 67
• When I find "2"(after), "0"(after), "8"(before) in "123456789"
  It shows → Not contain
  I need it to tell me "5" has been changed
  I tried to replace "Not contain" with "No (get at)"
  It shows → No 8 (not No 0)(because "8" is the last )

When you write:

"2"(after), "0"(after), "8"(before) in "123456789"

what should you get?

Oh, sorry, I was wrong
"I need it to tell me "5" has been changed" is incorrect
Anyway, when I write:"2"(after), "0"(after), "8"(before) in "123456789"
I need an alert: "There is no 0"

Your blocks are better than mine
I just made a small change

Then your blocks show "error in block 0", "error in block 98"
My blocks only show "error in block 0"
Your blocks are more convenient
