How to get duplicated MCs to mask?

programming flash

Okay I have a mc (_root.mainMC). Inside is a circle (mainMC.circle) and I have a line in the middle of that circle (mainMC.line).

I masked the two layers within so now all you see is a line. I duplicated the line using actionscript (mainMC.line2) and rotated it 90 degrees. You should see a plus now but it’s not masking. Any ideas?

  1. Unmasked.
  2. Masked. The line is duplicated and rotated using:
mainMC.line.duplicateMovieClip("line" + 2, this.getNextHighestDepth());
mainMC.line2._rotation = 90;

However, you can see that the second line is not masked.

  1. How I want it to look. The line will be duplicated numerous times.

Any clues?
