Okay,

I think I finally solved this. I just found one more place in the diagram in Excel (the FOURTH) where I can set the number_formatting. I set it to Currency, too - what perfidy is that, giving the user several places for the same setting, with one potentially overruling the others ...
It looks good now, even after running the macro several times - but it was so yesterday, so I'll wait till tomorrow.

Best regards,
