The Microsoft Excel ISNA function can be used to check for a #N/A (value not available) error. The ISNA function is a built-in function in Excel that is categorized as an Information Function. It can be used as a worksheet function (WS) in Excel. As a worksheet function, the ISNA function can be entered as part of a formula in a cell of a worksheet. The syntax for the ISNA function in Microsoft Excel is:
=(A2+B2)*C2. The parentheses tell Excel that you want this operation performed before the multiplication. If cell A2 contains the number 5, B2 contains the number 10, and C2 contains the number 2, Excel adds 5 and 10 to equal 15 and then multiplies this result by 2 to produce the result 30.
