FX formula in power apps form

[Bergs]

Hey Team,

I have created a workflow and power apps form in order to book in a meeting in 4 available time slots on tuesdays and thursdays - this will continue to run each week.

I want to make sure that once a timeslot has been taken for a given day that no one else will have the option to book that time slot. I am assuming that I will need to put logic into the Fx bar in my power apps form to enable this.

My two fields are Date (standard date field no time) and a choice column titled Available Times with the following options (2.30pm, 2.45pm, 3.00pm and 3.15pm)

can someone please assist.

Thanks team
