Hey zentara, Thank you for your response. And sorry as of now I don't have code its just an idea. I wanted to take few parameters from user but parameters on window 3(consecutive window) are dependent on parameters chosen from window 2 so I wanted different windows for different parameters and its always good to have only one window open at a time so I asked this question. Your code explains it pretty neat I think if I incorporate method for button "ForgetPack" with "Next" that should work, I'll work on it over this week and let you guys know about code Thanks again :)
