And how do I get my Excel to calculate and update formulas automatically again?

Don't worry, most likely your Excel is all right, and you will get all the answers in a moment.

: Excel formula not working correctly, it returns an error or a wrong result.

This section provides a summary of the most common mistakes people make when creating formulas in Excel and solutions to fix them.

At first sight, they look like normal numbers, but Microsoft Excel perceives them as text strings and leaves out of calculations.

The visual indicators of text-numbers are as follows: The below screenshot shows that even a simple Excel SUM formula may not work because of numbers formatted as text: To fix this, select all problematic cells, click the warning sign, and then click Convert to Number: In some cases, however, neither green triangles nor the warning sign appear in cells.

Microsoft Excel displays the parentheses pairs in different colors as you enter them in a formula.Golden Wing You'll need to include the 4th argument of the VLOOKUP function.Use this: =VLOOKUP(Section2Sum, Section2Table Lookup,2,0) Instead of this: =VLOOKUP(Section2Sum, Section2Table Lookup,2) That 4th argument dictates whether VLOOKUP looks for an exact match (0) or an approximate match (1)...which is the default..requires that the lookup values be in ascending order.Example: A1: 1 A2: 5 A3: 9 A4: 8 B1: 8...value to find If C1: =VLOOKUP(B1, A1: A4,1,1) it returns 5...because 9 is larger than 8, so the previous item is used.

If C1: =VLOOKUP(B1, A1: A4,1,0) it returns 8....because 8 exists in the lookup list. I have done as you recomended and changed the formula to the following =VLOOKUP(Section2Sum, Section2Table Lookup,2,0) however now i only get #N/A which is stating Value Not Avaliable Error.If your formula is short of one or more parentheses, Excel displays an error message and suggests a correction to balance the pairs.Please see How to highlight and match parenthesis pairs for more information.When this happens, a bunch of questions immediately flash across your mind. Why doesn't this formula update its value automatically?
