Hi Members,
 
I have a SharePoint list as "Desk Reservation Details", with a column: Desk Name [Lookup column], these column allows multiple values.
 
I was developing a application for Desk Reservation. On the Power Apps screen I have added a 9 button controls from Desk 1 to Desk 9. Whenever the user selects a button desk name as Desk 1 and Desk 2 and clicks on a Book Button control, those values should be saved to the SharePoint list.
 
For the each desk button control, The code I used for all desk buttons:
 
OnSelect :If(
          Find("Desk1,", varSelectedDesks) > 0, 
           // If Desk 1 is already selected, remove it from varSelectedDesks
           Set(varSelectedDesks, Substitute(varSelectedDesks, "Desk1,", "")),
           // If Desk 1 is not selected, add it to varSelectedDesks
           Set(varSelectedDesks, Coalesce(varSelectedDesks, "") & "Desk1,")
          );

Fill: If(
      Find("Desk1,", varSelectedDesks) > 0,
      Color.White,  // Turns white if Desk 1 is selected
      var_ThemeColor   // Default color (or any other color you prefer)
      )

Visible: If(
         !IsBlank(
          LookUp(
            'Desk Reservation Details_1',
            'Reservation Date' = DataCardValue3.SelectedDate &&
            'Desk Name' .Value= "Desk 1" &&
             'Reservation Status'.Value = "Booked"
           )
          ),
          false,true)
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In Book button control, OnSelect property, i have used the code as:
Patch('Desk Reservation Details_1',Defaults('Desk Reservation Details_1'),{Title:ReserveTitle,'Reservation Date':DataCardValue3.SelectedDate,'Reserved By':User().FullName,'Reservation Status':{Value:"Booked"},'Desk Name':varSelectedDesks})
But, I am facing the error as "Does not match expected type table, expected type text"

 
 
 
 
 
 
 
 
 
 
 
 
How to save the selected Desk button names to SharePoint list, if the user select Desk 1 and Desk 2. 
Please, Help me how to achieve this. Thanks in Advance!

    You have caused yourself a lot of complication using a Lookup field here (they are not really necessary with Power Apps and I never use them). What you have not posted is the field name in varSelectedDesks with the Desk details - I have assumed Value here when using _Data.Value - change this if the name is different. You also need to use the List and Field name you are looking up. Please also confirm that varSelectedDesks is a Table variable as it appears that it may be Text.
    Patch(
       'Desk Reservation Details_1',
       Defaults('Desk Reservation Details_1'),
       {
          Title: ReserveTitle,
          'Reservation Date': DataCardValue3.SelectedDate,
          'Reserved By': User().FullName,
          'Reservation Status': {Value: "Booked"},
          'Desk Name': 
          ForAll(
             varSelectedDesks As _Data,
             {
                Value: _Data.Value,
                Id:
                LookUp(
                   YourOtherList,
                   YourLookedUpField = _Data.Value
                ).ID
             }
          )
       }
    )
