conditional color property based on date

I want to use an IIF statement to set the color property for a text box.
Here is my code that is not working:
=IIf(DateAdd('m', -6, Fields!Orig_expireDate.Value) <
Now(), "red", "black")Use " instead of '
( ' is a comment for vb, even in reporting services)
