Hey guys i have this code in data valididation. this basically does not allow a user to enter any data in Range R11:R30 if column O and P does not have data
So for example :
If O11 has data in it.
P11 does not have any data in it.
Now if i try to type any data in R11 , then it must stop me from inputting any data.
So i get a error message that user has restricted any data entry in cell. However the data still gets inputted even though I get error message.
Is it possible to make sure that data does not get inputted at all?
Code:
=COUNTBLANK($O11:$P11)=0
So for example :
If O11 has data in it.
P11 does not have any data in it.
Now if i try to type any data in R11 , then it must stop me from inputting any data.
So i get a error message that user has restricted any data entry in cell. However the data still gets inputted even though I get error message.
