What I would do is find your start and opening blocks on every screen and drag out all the components

Then try and run it again  
Then add one screen at a time until you find the fault

And then remove those last blocks and slowly add in every time you try until the era happens

Hey there! Sorry you’re experiencing this. Try the below solutions.

# Fixes:

- Insure that your **variable blocks** are defined and declared
- Check if you entered correct data to Firebase or Data Sources blocks
- Look for **incomplete blocks**
- Duplicate your screen and check if the error stays the same on the new screen
- Check [Thunkable’s Server Status](https://www.google.com/url?sa=t&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwif88yG8a-MAxUQpIkEHaYUMKwQFnoECA0QAw&url=https%3A%2F%2Fstatus.thunkable.com%2F%23%3A~%3Atext%3DNo%2520incidents%2520or%2520maintenance%2520related%2520to%2520this%2520downtime.&usg=AOvVaw3zhi6y7o_0sE-3G0t8K_yx&opi=89978449) if the servers are down
- Contact Thunkable support (last resort)
