Hello,
I created a timer for a display using two text areas. One is a text area with a single wildcard (i.e. minutes), and another is a text area with two wildcards (i.e. seconds). It runs fine for ~9 minutes and 4 seconds but then suddenly the text area with two wildcard randomly generates a ? on the second wildcard, and this occurs on both the simulation and on the hardware that I am running. The typography has the 0-9 wildcard ranges, for all font sizes used. There are rare occasions when the question mark (?) goes away, but I do not know at what time that occurs. Any help is greatly appreciated.
Here is the code that controls the timer.
