How do I shut down a function if the function is used again?

I'm attempting to make a gui that shows different sets of tips that are sectioned off and are chosen based on the players choice. The gui seems to be functioning well, the button for opening up the thing works well, the section opens the respective tips, but when I close out of one section and decide to click on the other section, when I click the button that takes me to the next page or that takes me back, the display may show the text that is stored from the other dictionary. I'm pretty sure the problem is that when I switch to the other section, the previous function is still active since the output shows the Page number/All pages ratio (Line 100/118)print("Next "..Page.."/"..#TypeOfHelp)for both section selected. Is it possible to shut down one function, preferably via the exit button function (Line 91)

ExitButton.MouseButton1Down:Connect(function()
    Exit = true print(Exit)
end),

to stop conflicting actions?
