How to Change "Align to" option with script?

Hi.

Thanks a lot for your response.

I wire the script for aligning,

the problem is that this method work well in the case that selected one object or one group,

but when I select an cliped mask object or group that has clip mask and etc dont work corectly,

use of align panel of Illustrator dont this problem. you can use align for objec or group that inside of many clip mask or etc.

my solution is that use an Action for the align object, and call the Action from a UI dialog and command button.

every thing is ok. but new problem is that i can not change the "Align to" option from my dialog....

thanks again.

best regards.
