Hi, everyone I have a problem with Thunkable: I have been testing my app for the last 4 days, and I was able to login easily into the app. Right now, Thunkable does not execute my “navigate to Screen 1” and I cannot login again. I am using Google Sheets. I am sure that these blocks worked perfectly for me ![Screenshot 2023-10-18 at 15.00.51](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/b/5b898410b9e1559f696e42d7f14d111b6518dc4d.png) ---

Hi @a.ordokovlljpwq, if it never navigates to your Home screen, it seems like the issue is in one of your `if statements`. Have you tried adding in some debugging steps? One of our Power Thunkers @tatiang has a wonderful tutorial on how to debug here: > [@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… This is worth a look and adding into your click event here to see what might be going wrong. ---
