SQL Reporting question

Downloaded it to notepad to modify and upload back to SSRS. Basically it shows how much life a product has left, 0 days is red, 1 day is orange more than 1 day is white (no concern)

=SWITCH(DateDiff("d", CDATE(Now()), CDATE(Fields!date1.Value)) < 0,"Red", DateDiff("d", CDATE(Now()), CDATE(Fields!date1.Value)) 1,"Orange", DateDiff("d", CDATE(Now()), CDATE(Fields!date1.Value)) > 2,"White")
