Hi … I am new to GH and I am trying to use Expression.

The Expression i need is ((( 90 < x < 180 )) but i get a Syntax error: Right hand value of operator < is Null.

How to make it a correct Expression.

Plug some number in `x`

input. This input doesn’t have a defined type, so GH doesn’t know if you want a 0 or 0.0 or “” or {0.0, 0.0, 0.0}… so its null when empty and the operation can not be performed.

thanx for you answer. Do you mean that i can not have a list with the numbers between to numbers ( in this Example 90 and 180 ).

Or is there any other Method.

`Expresion`

is a evaluator, you give `x`

and get `r`

. You need a number generator, try with `Range`

component.
