You have redfined PushButton for no reason, so you're not using the module you claim to have studied. I have no idea why, or what you think this should be doing. You assign a value to $result, and print it to the screen. Nothing more. Why don't you actually read and understand the example code for pushbutton I pointed you to yesterday. Note that your code doesn't do anything like this. Learn from a working example and apply the working method to your problem. Please use code tags when posting code, advice to do so is displayed each time you post and in How do I post a question effectively?.
