hi jacob,
it's helpful but i need further help

(1)error message should pop up while i cross cell C1/D1/E1 without filling
it.
right now its showing even if i am at cell A1

(2) If i fill C1 but left blank D1 & E1 message should only be for D1 &E1

To make sure these fields are filled...

1. Select the range or the entire worksheet.

2. Enter the below formula in DataValidationCustom and uncheck Ignore blank
=AND($C$1<"",$D$1<"",$E$1<"")

3. Enter an error message say "Cells C1,D1 and E1 are Mandatory" in Data
ValidationError Alert....and click OK.

4. Select the cells C1,D1,E1 and clear all from EditClearAll


If this post helps click Yes
