Hi @Faribeiro

Your formula is basically correct. However, you can't set values directly in other fields. You'd need to set variables and use those variables in the corresponding properties.

So, your first formula:

// incorrect If(Connection.Connected,Button2.DisplayMode.Edit,Button2.DisplayMode.Disabled); // correct If(Connection.Connected,Set(gblDisplayMode,DisplayMode.Edit),Set(gblDisplayMode,DisplayMode.Disabled))

Now you just need to set gblDisplayMode to the Button2.DisplayMode property.

Your second question is the same. Set a variable instead of trying to set a value to a different field directly.

// incorrect Dropdown1.Selected.Value = Text(Today(), "[$-en-US]mmmm") // correct Set(gblToday, Text(Today(), "[$-en-US]mmmm")

and then set the gblToday variable to the Dropdown1.Default property. Alternatively, you can set Text(Today(), "[$-en-US]mmmm") directly to the Dropdown1.Default property.

I hope this helps.

Consider the following - Instead of setting a variable (very much overused in PowerApps), have your control derive its state from the Connection object. Set the DisplayMode property of Button1 to the following:

If(Connection.Connected, DisplayMode.Edit, DisplayMode.Disabled)

As for the DropDown - you need to set the Default property of that control to what you want. If it is truly a DropDown, you cannot select multiple items, so default is the only property you need to deal with. Default formula:

Text(Today(), "mmmm")

No variables needed for either.

I hope this is helpful for you.
