Error al pasar datos de xml a tabla en access

[lisseth]

saludos gracias por contestar, eso hice y funciona, porque lo corro con los breakpoints y me puedo dar cuenta que los valores ahora son 132.54 por ejemplo pero ahora me sale este error:

Server Error in '/xyz' Application.

Line 80: .Parameters.Add("@val2", OleDbType.VarChar).Value = val2bod_num
Line 81: .Parameters.Add("@val3", OleDbType.Double).Value = val3bod_dim
Line 82: .ExecuteNonQuery()

Y no se porque me sale ese problema si antes no me salia, ademas que campos permiten claves duplicadas no deberia salir eso!
