I hope this is an easy fix, but I cannot see why this is happening.
Numbers in column B, formula in Column A
Formula: =IF(B1=B2,1,2)
When I fill this formula in series in column A, the result shown is always 1, even when the result should be 2. When I click on a cell where the result is 1 but should be 2, select the formula bar, and hit enter, the correct result, 2, appears in the cell. This indicates to me that the formula is not wrong, but that Excel is not calculating the formula.
Why is Excel not calculating the result for each cell until after I enter the formula bar for each cell? Is there some option that is switch on/off?
(and yes, the formula increments for each row, so the fill series test is b1=b2, b2=b3, etc.. etc.)
