Thread: Adding a 'close window' button

How can I add a button that closes a popup window?

Insert an Advanced button. It is that ABC button next to the standard Button. Size the button as required by dragging its handles.
Double-click the button to rename it as required.
Click outside button again.
Now right-click the button and select Properties.
In the General tab - Properties, give it a name.
For Button Type, select OnClick.
For OnClick Action, select Close the Current Browser Window.

Click the Styles tab and format colours, etc. as required.

Thank you very much!

...and Bless you too!
