datediff function

[Guest]

Hi there,
I got a problem that is bodering my for a while. I have a form with 2 dates
one is permanenet and the other is showing the actuall date. As a result i
would like to get a numeric value ( a count of days between the permanetn
value and actuall date). I have tried a datediff function and it doesn't work.

[Field where you want the result]=[PermanentValue]-[ActualDate]

it will work if you have the PermanentValue is as Date Properties.

if you have not a field with the actual date, you can create it making not
visible.


Thanks.
