Добавила так ->
document.write('<frameset rows="*, 30" scrolling=no noresize frameborder="0" BORDER="0" framespacing="0">'+
'<frameset rows="50%, *, 0" scrolling=no noresize frameborder="1" border=1 framespacing="0">'+
'<frame name="main" src="main.php?top='+rnd+'">'+
'<frameset cols="*,220">'+
'<frame name="chat" src="buttons.php?ch='+rnd+'" target="_top" scrolling=YES FRAMEBORDER="5" BORDER="5" FRAMESPACING="0" MARGINWIDTH="0" MARGINHEIGHT="0">'+
'<frame name="online" src="ch.php?online='+rnd+'" target="_blank" scrolling=YES scrolling=YES frameborder=0 BORDER=0 framespacing=0 marginwidth=0 marginheight=0>'+
'</frameset>'+
'<frame name="refreshed" target="_top" scrolling="no" noresize src="refreshed.html">'+
'</frameset>'+
'<frame name="bottom" scrolling="no" noresize src="buttons.php?'+rnd+'">'+
'</frameset>');
