Hello, I am creating a Flex Office application to allow users to book offices. When the user chooses a date on the first screen, he can then click on a desk on the second screen to reserve it.
Once done, the SharePoint list will populate with each user's reservations.
Screen 1 :

Screen 2 :

SharePoint List :

"Name" column: Type People Picker (Indicates the name of the person who booked the room)
"Date" column: Type Date (Indicates the date of the reservation, chosen on the calendar screen on power apps)
"Number_Office" column: Number type (Indicates the office number reserved by the user)
What I would like to do :
I would like that if, for example, office number 1 is already reserved by someone, then the blue dot corresponding to office number 1 on screen 2 is red. But I don't know how to do that. Could you help me please? Thanks in advance ! 😄
