ODBC connection 8.0 won't write to database

[Jesper Ahlers]

Hi
I'm using the following connection string on my 64 BIT Win10 pc in a ASP Classic program.

Driver={MySQL ODBC 8.0 ANSI Driver};Server=127.0.0.1;Database=my_db; User=root;Password=MyPW;Option=3;'
It works fine with reading the database, but when updating I get the following error
[MySQL][ODBC 8.0(a) Driver][mysqld-5.5.30]The number of parameter markers is not equal to he number of parameters provided

I have an old 32bit pc running ODBC driver 3.51 which works fine.

Shall I in one way or another give access to updating the database?
If so please tell me how

Thanks a lote
