Changing a column value of a SharePoint element listed in a gallery from a PowerApps

[FacundoGorla]

So I'm currently trying to build a Inventory App and I was playing with the data of a column that indicates if a PC is avaible or not.

Currently I show that status with an icon changing color depending of the choice.

I want to change the actual value of that status column from the item from avaible ("Libre") to unavaible ("Ocupado") whenever I click on the Icon itself. I manage to do it but i wonder if there's an easy way to do it. The Choice column name is Disponibilidad.

I used Updateif but I cant understad how the ID inside it works, I set it on 1 and it works but I truly don't know how.

I'm thinking of using a lot of buttons that will change column values so I want to learn the right way to do it. 

Here's the code currently working:

UpdateIf(
    'Proyecto Facu';
    ID = Gallery1.Selected.ID && Gallery1.Selected.Disponibilidad.Value = "Ocupado";
    {
        Disponibilidad: {
            '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference";
            ID: 1;
            Value: "Libre"
        }
    };
   ID = Gallery1.Selected.ID && Gallery1.Selected.Disponibilidad.Value = "Libre";
    {
        Disponibilidad: {
            '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference";
            ID: 1;
            Value: "Ocupado"
        }
    }
)

If it is a choice column then you shouldn't need the 'ID: 1". If it is a lookup column then you would need it and the value would be ID of the item in the lookup list.

Oh, great. So I can remove that part and it will continue to work, besides that is this well done?

Hi @FacundoGorla ,

Is there any error or red lines under this formula in PowerApps? If not, then the formula should work as expected.
