Loop through Multi-Dimensional Array

At first glance I think the problem is that if you use "repeat for each" you can't make a change to anything inside that loop. You have to kick what you are changing out to another variable.

This is the main idea:

repeat for each line k in v
if line k is target_line then
put new_line & cr after h
put line k & cr after h
end repeat
delete last char of h -- last cr

now the variable h holds what you need
