Hi Stefan,

thanks for you quick reply.

Becuase I was following the model used for many of the frontends for the ND280 FGD.

Perhaps things have changed in the 10 years since the FGD SC code was written. I can do it 
differently but doing it that way seemed naturual since around 90% of the frontend code that I
have see does it that way.
