Ignore the first confirm window and pay attention to the second

Hi All, If do anybody know how to close one confirm window in automatic and pop-up another confirm window? In the process of my skill code, I need to ignore the first window and only see the second. It is some prompting information, so I only need to pay attention to the second. I attempt to use axlSetVariable("noconfirm" t), but it will ignore all of windows, the information will appear in skill window. It isn't "wf" issue in axlOpenDesign(). Please give me your advice, thanks a lot. Regards
