Hi,

I think in your case you have checked the "multiline data" in your panel setting and you have an extra entree below the "0" input that's not visible.

When you entered the 0, you hit enter which created this entree.

See the attached image.

• Image 1 is your panel, and the extra entree is not visible because you have the multiline data checked.
• Image 2, right click the panel and uncheck the "multiline Data", which results in
• Image 3, here you can see the <empty> entree, which results in the error (although the mass addition still runs)

When you have your panel set without multiline data checked, just delete the empty entree and it should function.

Let me know if this worked,

Cheers,

Arie

• did the exact same thing but didn't work dunno why? clearly panel and duplicate data outputs are not getting accepted even after flattening
• wrong screenshot added here refer above comment
