Blank Entry Validation in an Expression

Hi,

I have created a validation on an expression to prevent a future date be entered but cannot work out how to write an additional statement in an expression to allow a blank entry in a date field.

Please would any be able to help.

Many thanks,

Gary

Hi,

I'm not sure what exactly you're trying to do. Are you trying to check for a blank date? If so, you can use something like:

YourVariable = NullDate()

Hi, thanks.

That's worked perfectly.
