Werner,
Would you please take a look at the attachment?
Appreciate so much.
I think I understood your problem already and my question was "whats wrong with omitting the material selection box in the second series of list boxes?".
I have assigned Md the value of Material, but of course you could have used Material itself in the last listboxes and get rid of Md completely.
One additional point: I see alot of list boxes which will present one value only. If you are absolutely sure, that a specific property will always be a unique value, whatever the user choses for the other and you think it doesn't make much sense to present a listbox where there is no choice, you may use something like Cd:=Filter(Z_diagram,stack(Md,ud,fd))[0 instead.
