I'm hopeful you will feel free to correct these anytime you have the energy, I am still learning and hate to share incorrect info.
It took me a long time to learn that things not working in Wappler often means stop, think, close and reload, possibly reboot, then try again. Your videos including some of these things helped me realize things won't always work even when you do it "right", and there usually isn't an error message about it so you just need to try again a few times.
