thanks for your answer. You are right. I should use findfield in that case. This is some old code and I think I just did it that way, because the ol IBO allowed me to do. Now I have to deal with the sins of the past.

I will change that, but I do not really know where in my code similiar constructs are used. Have to find a way to find them.

So not really a bug of IBO but one of my younger me doing some dirty coding.

Best Regards

Helmut
