First of all, I would like to make it clear that English is not my mother tongue and I don't speak it well, so I'm sorry for any mistakes.

I'll present the line where I'm having problems below.

```
vetor = iris$Sepal.Length

for (i in vetor) {
mean = mean(vetor)
  SD = sd(vetor)
  zscore = ((i-mean)/SD)
  print(paste("The z score number", 1:150, "is",  zscore))
}

```

What I wanted to happen is that it returned

"The z score number 1 is ..."

"The z score number 2 is ..."

And so on. In fact, he actually returns it to me, but when he finishes he starts again and repeats it at least 13 times. I don't know why this is happening.
