Totally follow the tutorial to create the parabola curve, but got stuck the EVALUATE component… What is the problem here? [10]

Hi, Maybe you should change ‘Variable x’ to ‘x’ and ‘Variable y’ to ‘y’ …?

It is because you are using full name mode.

Thx for replying, if you mean this, it doesn’t work… Or what do you mean? [27]

Hi - check this post for more information: [image] Expression 2*π* x*y Grasshopper 1.Uncheck “Draw Full Names” As I mentioned above posting, please read the previous postings carefully. 2.Remove all double quotation marks. [cap] [Canvas%20at%2002%3B26%3B13]

thanks for your replying, but it still doesn’t work at all… [56]

What’s the error you’re getting? You can see it by clicking on the red balloon in the upper right corner of the eval component.

The errors show on the first pic, can you see that?

Yes I can, it doesn’t make sense that that error doesn’t go away after renaming the inputs to no longer have whitespace. So I was wondering if there’s a different error now. It could be a windows/macOS difference, but maybe something else is going on.

i have the exact same issue, any solution?

Rename your inputs so they don’t have spaces in them. Not Variable x but just x.

Why does my EVALUATE component show errors?
