How to null date if blank

[JohnMald]

Hello,

I am trying to create a calculated column using the formula but want the calculated filed to be blank if the “IC” date is blank. Can someone help please

=[EAS]-[IC]

[#2]

=if(isblank([IC]),"",[EAS]-[IC])

[#3]

@JohnMald Try using below formula:

=IF(ISBLANK([IC]), "", [EAS] - [IC])

Note:

1. Sometimes comma(,) does not work in formula (I am not sure but it is based on something language or regional settings on your site). So in that case use semicolon(;) instead of comma(,).
