I've done this a few times but this time it's not working for some reason.
In my party frames I've attached a 'Shade object conditional alpha'.
Flag variable: Vars Unit In Set: Unit In Range (2,4)
When the party unit is in range, they're at 1 alpha. When it's false, they're at 0.25.
The error that comes up is Invalid Flag Variable.

Is what it looks like ^
I've also tried to make a fileset with range and link it through Vars Unit In Set / Fileset / InRange but the same error happens.
