title: Excel formulas not working correctly in all cells
body: <p>The same formula does not work in some cells. (same problem in other sheets) The cells seem to be random. I have Auto Calculate on and have been careful to have all cells formatted the same, etc. (tried several options). The formula is: =IF(U110&lt;>$X$1,"ERROR IN TIMING",""). What is wrong?..Working in Excel 2013.Some cells will calculate as ERROR IN TIMING, while others will remain blank, as they should. I have even tried the Array brackets. </p>
