Get the reference of a window

[#1]

Hello,

I want to be able to delete a box when closing a data table. 

In the code below I want to close Big Class, the text Box of w to be deleted. 

Names Default To Here( 1 );
project = New Project();

project << Append(
 w = New Window( "Window", Text Box( "Window 1" ) )
);
project << Append(
 w2 = New Window( "Window2", Text Box( "Window 2" ) )
);

dt1 = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt1 << On Close(
 w["Window 1 ?"] << Delete;
);

My problem is that when I close BigClass, jmp shows me "unresolved name for w". Is it possible to recover the reference of the window w which seems to be lost after opening the data table. 

Thank you in advance for your answers

Accessing the window to close based upon using the Window() function with the window's name worked for me

Names Default To Here( 1 );
project = New Project();

project << Append(
 w = New Window( "Window", Text Box( "Window 1" ) )
);
project << Append(
 w2 = New Window( "Window2", Text Box( "Window 2" ) )
);

dt1 = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt1 << On Close(
 window("Window") << Delete;
);
