Script for dashed lines in illustrator

Hey all, 

I have to make a lot of technical drawings of garments at work, and i've been trying to create a script that would allow me to make different types of dashed lines super fast.

The script I use (or at least want to use) is supposed to offset the line to a given distance (this part works like a charm), and then transform the new line into a dashed line.

However, whenever I try to script a dashed line (that is not the default setting of 12pt/ 0pt), it just won't work (or kinda work).

What it does, even though I change the settings (to 2pt/2pt), is that it only picks up the first information (making it 2pt/0pt), making the dashed line appear full, since there is no space in between the dashes. 

Does anyone know how i could make this work? Or maybe just change the default dashed lines settings so that i don't have to change them when recording the script?
