Jquery slidetoggle without moving bottom content

Jquery slidetoggle without moving bottom content

I got this function which show up the second frame when the button is clicked. This is doing what i want but the problem is when i clicked it again, it shows the first frame, i only want it to show the 2nd frame. I have another button that does showing the first frame though.
Thanks for the help.

$(function() {
var pos = $("#iframeE").position();
$("#iframeO").hide();
$("#wrapper, #iframeO").height($("#iframeE").height());
$("#wrapper, #iframeO").width($("#iframeEt").width());


$("#btn").toggle(function() {
$("#iframeE").stop().slideToggle(); $("#iframeO").stop().slideToggle();
}, function() {
// $("#iframeE").stop().slideToggle();
// $("#iframeO").stop().slideToggle();
});

});
