Is dop2000 still around by any chance? I actually used his tutorial and another one he sent me, so he might actually be able to help. Dop, if you're around let me know, I'll just share the entire capx!
Here's the capx in case you or anyone else gets a chance to take a look, but basically everything else works! You choose whether to time yourself or beat the clock, you choose the suspect, type in your user name and submit. The info properly transports to Google Sheets. The problem is that when I try to read google sheets back, my text box keeps just outputting "O."
