trying to work on some lead times through by obtaining the difference between 2 dates
Committed/Done Diff = IF([DATE1] > [DATE2],"",DATEDIFF([DATE1],[DATE2],DAY))
what i am trying to achieve is have if the date 1 is greater than date 2, then leave field as blank
if date 1 is not greater than date 2, give me the date difference between the 2 dates
the error i get is
"expressions that yield variant data-type cannot be used to define calculated columns"
not sure what i am doing wrong
any help would be appreciated
