How do I count for something that has not already been used in a cell from a multi cell dropdown?

Hi all,

I need help!

From this list of machines, I would like to know which machines are available on a particular day..

I have a date column on my sheet.

How would I solve this?

Much appreciated!! Thank you!

Do you have a separate list of machines (it could even be in your sheet on a hidden column...)?

If not, then create one.

then:

1. Create Multi-Dropdown Field called 'Used Machines'. should have column formula: =JOIN(COLLECT([Sinker Machine]:[Sinker Machine], Date:Date, Date@row), CHAR(10))
2. Create Multi-Dropdown Field called 'Available Machines'. should have column formula: =JOIN(COLLECT({reference to machine list}, {reference to machine list}, AND(@cell <> "", NOT(HAS([Used Machines]@row, @cell)))), CHAR(10))

When you enter a new row and put in a Date the available machines column will populate
