Hi!

I know I can use chs so the user can type in a word:

string name = chs("name");

…but I don't get how to use that string to decide the name of a group.

i@group_name; …..??

You can mix in a bit of expression language to make this work:

@group_`chs("group_name")` = 1;

Oh,

How did you make the symbol right before chs and after )? I can't figure out the keyboard shortcut for that…

you can also use group binding in Bindings tab to define which group is bound to which variable in the wrangle

It's the same key as ~ on a US keyboard layout… not sure what you're using. It forces an expression within to evaluate as a string.
