Hi guys,

Thanks a lot for your publication, just few words to advise.

I use this approch, and I meet many problem with the checksum process.

So if you have some Null value in the key the checksum failed or return an "strange" value.

So take care to controle all fields have a value and best way be not null, and to reduce failure of cheksum process, i add a "|" between each fields, add an IsNull function 'In case Of".

Regards
