I am currently trying to implement a GUI for a task at work. I have found some open source code (see below) where we make a GUI having 3 pages where one can go between the pages using next/previous buttons. If you run the code you'll see what each button and so on is indended to do.
However, when you run the code and click the "count++" button, the overall count increases by one and not the count for the individual page (e.g. being on page 1 and clicking the count++ 4 times, still makes the count for page 2 or 3, 4 as well, and not zero). The same problem occurs when I try to update the text in each of the textboxes on each page (supposed to be number of clicks), as it won't update. I am not sure how to actually get to the textframe for each individual page.
Any suggestions on where to go from here? In the long run I would like to have scroll-down menus where the selections will be put onto each individual text-frame.
Thanks,
