Hi,
I am creating an Edit Form in Apps , with the data source in SharePoint.
I am trying to insert a formula and I do not understand what I am doing wrong.
If(DataCardValue10.SelectedItems.Value = "Update",White,Transparent)
I am trying to make a circle border color transparent or white depending of the choice filed (DataCardValue10 is a choice field marked into SP, "Update" is one of the options in drop down list)

Could you please help me to understand what I am doing wrong and what needs to be done in order to have the formula that is looking to that field options?
Thanks you!
