[Newbies] "Print specific integers" Error message, how to improve ?

[Benoit St-Jean]

Q1) Because you increment n when you hit 123, so the index is now 8 but your array only has 7 elements. 
Q2) You could do it in a zillion way, the simplest one is like:
| myArray|

myArray := #(2 32 44 67 89 111 123).

1 to: 130 do: [:i | (myArray includes: i) ifTrue: [ Transcript show: i; cr ]].

 Hello, *what I want is:*
>From integers 1 to 130, I want to print some specific integers already given
in an array.
They are: 2 32 44 67 89 111 123 which are stored in small-to-big order.

*Here's my codes:*

|a n myArray|

myArray := #(2 32 44 67 89 111 123).

n := 1.
a := myArray at: n. 

1 to: 130 do: [:i|
    i = a
    ifTrue: [
        Transcript show: i; cr.
        n := n + 1. 
        a := myArray at: n.
        ].    
    ].

The output is very good except for an Error Message.

By my current level, I have no idea why that Error Message appears. 

Q1: Why  Error Message appears ? 
Q2: How can I improve that?
