I have a simple countdown timer that Professor JimJam and Brad Yundt wrote for me that I have attached. I'm trying to simply do two things with it. 1.) provide a simpler input capability for users by simplifying the first tab (details on first tab) and 2.) also include a reset button to take the timer back to -0- or start in the event that you want to set a new time.
This is one of three asks for this timer but I have broken it down into steps.
