hi,

I have a table with four columns.

I need to validate one of the column .  Error should be thrown where-ever that particular column contains zero value. 

Error should be shown only where there is zero, it should not show error in other rows where there is valid non-zero value.

Example :- Age property in a table ( Page-list ) on UI, UI should throw error where-ever there is value as zero in age column. 

What logic or function we can use to achieve this in validation rule
