I've created an interactive animation. On load, a number
appears in the dynamic text box. When button one is pushed, the
number needs to change; when button two is pushed, the number needs
to 'clear' - be replaced by '-.-'.
The '-.-' shows up; the second number does not. For
reference, in the code below, the 4.5 is in temp_txt on load; when
the minmax_btn is pressed, no numbers show up in min_txt or
max_txt; when the reset_btn is pressed, the '-.-' shows up in
min_txt and max_txt.
