Please goto Data Validation > Custom > uncheck Ignore Blank and paste this formula in the same provided
=AND(ISBLANK(I48)=FALSE,B32>=I48,I48>0)
Hopefully it works.
Hi pallu,
Do you want data validation in Col J and L of first sheet. I mean you want a fix so that no one can enter more then 3 in Col J and more then 2 in Col L?
Do you wan similar validation for CL/PL so that if a cell contains value for SL one can not enter a value in corresponding CL/PL.
