Duplicating dynamic text box

I can’t for the life of me figure out how this works. I have tried several different methods found in these forums and none work. I am trying to duplicate an MC 11 times - that works fine. But the MC has a dynamic text box centered on it. I would like the first one to say “1900” and each one after to be increased by 10. So the second one says “1910”, the third says “1920” and so on. I have this code on an MC called “timeline”. The MC I am trying to duplicate is called “bar” and is with “timeline”:

for(i=0; i < 12; i++) {
_root.timeline.bar.duplicateMovieClip(“copy”+i, i);
ext = _root.timeline[“copy”+i];
ext._x = 125 * i;
ext.year.text = “1900” + 10;

I have also tried this:
amount = 11;
year = 1900
while (amount>0) {
duplicateMovieClip (_root.timeline.bar, “mc”+i, i);
_root.timeline[“mc”+i]._x=_root.timeline.mc._x +(125*i)
_root.timeline[“mc”+1].year.text += 10;


but to no avail.

What am I not getting here? :frowning:

p.s. The dynamic text box on the bar MC is called “year”. I have tried making that the var as well as the instance name and still no luck. Which is it supposed to be?
