It’s not clear to me that you’ve tried debugging your blocks in any methodical way. You can try this: > [@Debugging in Thunkable X (Video)](https://community.thunkable.com/t/debugging-in-thunkable-x-video/849471): > > I thought I’d share a process I use for debugging my projects. It involves creating a function that can be used over and over throughout the code blocks in order to help determine where things are going wrong, whether or not certain blocks are ever triggering, and what the values of several variables are. Here’s a screenshot of what I’ve set up: The real power comes from being able to quickly change the delay (and even set it to 0 seconds) or just remo… And then report back where in your code the problems seems to be. For example, you are checking the value of a switch and only navigating to a new screen if the switch value is true. Is it actually true when you assume it is? How have you confirmed that? Another method is to add a vibrate block and test it on a mobile device. If you feel the vibration, you know that part of the code was run. Is the user being taken to a _different_ screen than “Food Category List”? You said that happens automatically. Nothing in Thunkable is automatic. You either have a block that does something or you don’t. More details would be helpful. --- _[View the full topic](https://community.thunkable.com/t/sign-in-with-firebase/1690595)._
