Error in running GUI

Hi everyone, I got problem in runnin GUI. The 'selected Button' always show Unrecognized method, property, or field 'selectedButton' for class 'skin'.

 % Selection changed function: SkinProblemButtonGroup
        function SkinProblemButtonGroupSelectionChanged(app, event)
            %turn on the button
            selectedButton = app.SkinProblemButtonGroup.SelectedObject;
            switch app.selectedButton.Text
                case 'Hyperpigmentation'
                    app.HyperpigmentationButton.Value = true;
                case 'Acne'
                    app.AcneButton.Value = true;
                case 'Dullness'
                    app.DullnessButton.Value = true;
            end

But in previous part, there is no problem with this commad

 % Selection changed function: SkinTypeButtonGroup
        function SkinTypeButtonGroupSelectionChanged(app, event)
            
            %turn on the button
            selectedButton = app.SkinTypeButtonGroup.SelectedObject;
            switch selectedButton.Text
                case 'NormalSkin'
                    app.NormalSkinButton.Value = true;
                case 'CombinationSkin'
                    app.CombinationSkinButton.Value = true;
                case 'DrySkin'
                    app.DrySkinButton.Value = true;
                case 'OilySkin'
                    app.OilySkinButton.Value = true;
                case 'SensitiveAkin'
                    app.SensitiveSkinButton.Value = true;
            end            

Can anyone tell me what's the problem? Thank you

Hi @poor kitty,

The error occurs due to the following line in the code:

switch app.selectedButton.Text    

Here, 'selectedButton' is being referenced as a property of 'app' (app.selectedButton), but in the function, 'selectedButton' is defined as a local variable.

Therefore, the correct approach is to use the local variable directly, as:

switch selectedButton.Text

I hope this helps resolve the issue.
