When i try adding a new patient for testing purposes system refuses to update list but gives me Index (zero based) must be greater than or equal to zero and less than the size of the argument list. Error if anyone can take a look at this I'd be very happy

The error message is telling you exactly what is wrong: your format string has 8 slots ({0} through {7}) but you are only passing 7 arguments.
