Frequently Asked Questions
Question:I am trying to get Excel to check different boxes and check if there is text/numbers listed in the cells and then spit out "Complete" if all 5 Boxes have text/Numbers or "Not Complete" if one or more is empty. This is what I have so far and it doesn't work.
=IF(OR(ISBLANK(J2),ISBLANK(M2),ISBLANK(R2),ISBLANK (AA2),ISBLANK (AB2)),"Not Complete","")
Answer:First, you are correct in using the ISBLANK function, however, you have a space between ISBLANK and (AA2), as well as ISBLANK and (AB2). This might seem insignificant, but Excel can be very picky and will return a #NAME? error. So first you need to eliminate those spaces.
Next, you need to change the ELSE condition of your IF function to return "Complete".
You should be able to modify your formula as follows:
=IF(OR(ISBLANK(J2),ISBLANK(M2),ISBLANK(R2),ISBLANK(AA2),ISBLANK(AB2)), "Not Complete", "Complete")
Now if any of the cell J2, M2, R2, AA2, or AB2 are blank, the formula will return "Not Complete". If all 5 cells have a value, the formula will return "Complete".
