Cast an employee to a column based on Due Date falling within a Timeline

So I have a problem - trying to find a work around for the scheduling. I would like to assign an employee into a column based on the task due date falling within their vacation dates Timeline column. If the task due date falls within the timeline column dates it would assign that employee to the PTO column for that task. Trying to do this with General Caster but not familiar with every way to express this.

=IF(AND({Date}>={Vacation Dates :arrow_lower_right:#Start},{Date}<={Vacation Dates :arrow_lower_right:#End}),“In Range”,“Out of Range”)
