Conditional Actions (is between)

Hello,
I need to make conditional displays:

  • When the item is equal to or less than 9
  • When the item is between 9.01 and 18
  • When the item is between 18.01 and 26.99
  • When the item is equal to or greater than 27.

I can’t do this! Could you explain to me how the “is between” option works?

If for example I decide is between 9 - 18 and the item is equal to 9, will this item be displayed?
and 18, will it be displayed?

I’m lost ! Thanks for your help.

is beetwen :

[a,b]
or
]a,b[
or
[a,b[
or
]a,b]

Thank you
