CATCH an error

Execute dbo.cuspRideSummaryDelete and pass an invalid @DateParm value of '1/32/2018' to see how the error is handled. The invalid date will be accepted by the nvarchar data type of @DateParm, but the error will occur when SQL attempts to convert it to a valid date when executing the stored procedure.
