>Hello. I have an application where the users can input a $0.00 value. I've tried Numeric(10,2) and Money as the data types, but it still says it cannot save the dataset becuase Cost is required. $0.00 is a valid input value.

I think you should put a break point in the Validation Rule for this property and verify if 0.0 is being determined to be no value. I presume since they would be inputing 0.0 that you didn't expect the value to be left null. Some of the framework validation determines 0 to be the same as empty.
