app designer does not get the value from edit field in panel

Hi All

I have an edit field that is inside a panel. It seems that when I call the value with app.variable , it can not be read. How to fix? am I using the wrong method ?

        % Value changed function: ColumnEditField
        function ColumnEditFieldValueChanged(app, event)
            app.col = app.ColumnEditField.Value;
            
        end

Hi Farzad, what is the error message displayed in the command window?

[farzad]

It says it doesn't know the variable.

Have you verified that the edit field is still named "ColumnEditField"? You can check by using the Component Browser pane in the design view

Alternatively have you created the 'col' property within the app?

It's correct what you've written and what Xavier suggested. You need to create a property col.

If col is a number, use col = [];

If col is a char, use col = '';
