Why are my formulas not updating when I make changes to my data?

1. Check if your data is arranged in a table with each column heading clearly labeled.
2. Check that each formula in the cells is referring to the correct column of data.
3. Check if any conditional formatting rules may be causing conflicts.
4. Check if there are any circular references that could be causing your cells to return the same value.
5. Check if your data is being filtered correctly.
