# Excel sums not automatically updating

Once you turn it on, it's on - even if you don't save the workbook!

A workbook of mine that worked fine for several years, when using Excel 2003, suddenly refused to update all the formulas, after a switch to Excel 2010. When someone tells you that formulas aren’t calculating, it’s probably because the Calculation setting has been changed to Manual, instead of Automatic.

VLOOKUP formula not updating automatically I have a spreadsheet that pulls data from a SQL database, compares that data, using VLOOKUP, to an array in another sheet and returns and sums data on a third sheet. Some of these cells are empty, since not enough data from the SQL query is available yet, but I copied it down all 1500 rows so that in the future, when I refresh the data from SQL, the formula will run and the cells will be populated automatically. It seems that each time I refresh, the formula is getting copied over out of order.

The VLOOKUP command looks like this: =IF(ISERROR(VLOOKUP('Ae XHD Data'! The VLOOKUP statement would look at E2, E3, E4, E5 and then jump to, say E10.

Click the Formulas tab on the Excel Ribbon, and click Calculate Now or Calculate Sheet.

In the tooltip that is shown in the screen shot below, you can see that the shortcut for Calculate Sheet is Shift F9.

Edit: I should have added that this can be applied to any formula.

The formula with "E2" for example -- is it on row 2.

You can use a named range for the range on the other sheet, at this point I don't see it making a difference in what is happening.

Or, go to the Excel Options window, and click Formulas.

Even if the Calculation option is set for Manual, you can use a Ribbon command or keyboard shortcut to force a calculation.
