I am sure I am making just a plain old dumb mistake but how in the world do I gan an answer/output from this? It pops up, respones, but when it's gone I don't have any value from the box at all :(

function correctdialoguefontsize
    d = dialog('Position',[700 500 250 150],'Name','');
%coordinates are x,y,length,height
    txt = uicontrol('Parent',d,...
               'Style','text',...
               'Position',[20 90 210 40],...
               'String','Which emotion do you recognize?');
           txt.FontSize = 12;
    btn = uicontrol('Parent',d,...
               'Position',[40 70 70 25],...
               'String','Angry',...
               'Callback','delete(gcf)');
           btn.FontSize = 12;
    btn = uicontrol('Parent',d,...
               'Position',[120 70 70 25],...
               'String','Fearful',...
               'Callback','delete(gcf)');           
    btn = uicontrol('Parent',d,...
               'Position',[40 30 70 25],...
               'String','Happy',...
               'Callback','delete(gcf)');
    btn = uicontrol('Parent',d,...
               'Position',[120 30 70 25],...
               'String','Sad',...
               'Callback','ans=sad');
           
end
