In a script? In a calculaiton field? What results do you want if the result is not greater than 1000 days?
Assuming a calculation that computes the number of days between the dates in two date fields:
If ( abs ( Date2Field - Date1Field ) > 1000 ; "Void" )
The field will be empty if the result is 1000 or less.
If the result is less than 1000 days I would like the actual number of days to be posted.
Let ( d = abs ( Date2Field - Date1Field ) ; If ( d < 1000, d ; "Void" ) )
Note: I used the absolute value function here so that if Date2Field is empty, the resulting large negative number will also result in "void".
Works!!! You always make it look easy.
