linq-to-sql

Hi folks, I'm trying to filter a set of records based on a sub-object's criteria. This compiles ok

recordList = recordList.Where(r => r.Areas.Where(a => a.Area == "Z").Count() > 0);

but this doesn't

recordList = recordList.Where(r => r.Areas.Where(a => a.Area <= "Z").Count() > 0);

giving these errors Cannot convert lambda expression to type 'string' because it is not a delegate type Delegate 'System.Func' does not take '1' arguments Operator '<=' cannot be applied to operands of type 'string' and 'string'

!= works ok, by any sort of less than or greater than operation fails.
