The # will always be the first character shown and it will be followed by the name of the particular error. Common ones could be:
#REF!
#VALUE!
#NUM!
If you see the # repeated, it indicates that the cell is not wide enough to show the value in the cell. It is not necessarily an error.
OR
A green triangle in the upper left corner of the cell
The error message that indicates a cell reference error is typically shown as #REF!. This error occurs when a formula refers to a cell that is not valid, often due to the referenced cell being deleted or moved. It signals that the formula cannot find the cell it needs to function correctly.
In the formula bar.
The cell contents are what is actually typed into a cell. This is not always the same as what is displayed. So you can type a formula into a cell, which would be its contents, and the formula will do a calculation and display a result, which is the cell display. When you look at the cell you would see the result of the formula, but not the formula itself. The cell contents are always displayed on the formula bar. If you just type a number in, then the cell content and cell display can be the same. What you could then do is to format the cell and the number would be displayed in that format.
That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.That is correct.
The formula will be entered and a calculation will be done and a result displayed.
If there is a formula in the active cell, then the formula will be displayed in the formula bar and the result of the formula will appear in the cell.
The proper name is the formula bar, but yes a formula or value can be seen there when you have entered a value or formula in a cell.

In the name box, beside the formula bar.
A circular reference occurs when a formula in one cell depends on the value of another cell, which in turn contains a formula that refers back to the original cell. This creates a loop where the two cells continuously reference each other, preventing Excel from calculating a definitive value. As a result, the software may display an error or warning, indicating that it cannot resolve the circular dependency. To resolve this, you typically need to adjust the formulas to eliminate the circularity.
Within the cell you may see an error which will always start with the # symbol, such as #REF! or #VALUE! You may also see a small triangle in the top right corner of the left corner of the cell, or an icon appearing beside the cell, though not in the cell next to it. If a formula has a problem as it is being typed, you may not be allowed to enter it and a message may pop up or an option showing you what can be done to fix it.
