Help with an error I don''t understand

Hey everyone,

I'm trying to make an image appear differently depending on the values of certain data. The statement that I am using is:

= IIF(DATEDIFF("dd",Fields!LastBackupDate.Value,Now)>15,"redball",IIF(DATEDIFF("dd",Fields!LastBackupDate.Value,Now)<8,"greenball","yellowball"))

And the error that I get is:

[rsRuntimeErrorInExpression] The Value expression for the image ‘image4’ contains an error: Argument 'Interval' is not a valid value.

Preview complete -- 0 errors, 1 warnings

When I preview the report I just get the typical white box with a red x where the image should be. I don't understand.

Thanks in advance,

Keith

Nevermind, argument needs to be "d". Thanks anyway!
