Problem regarding maps

Hi,
I have little knowledge on Java script, as I'm a Business intelligence analyst. In my application java script has been used for Manipulating Map reports.
I have the code like this.
function ResizeMap() {


//x = document.body.innerHTML;
//document.body.innerText = x;

var MC = document.getElementById('MainContainer');
var MD = document.getElementById('mapdiv');

while (MD.parentNode != MC)
{
MD = MD.parentNode;

}
//alert(MD);


Qva.Resize.Frame = MD;
var objectMgr = Qva.Resize.Frame.AvqMgr;

if (objectMgr) { objectMgr.Set(Qva.Resize.Frame.ObjectId, "resize", 'br:750:380', true); }
else {
var binder = Qva.GetBinder(Qva.Resize.Frame.binderid); binder.Set (Qva.Resize.Frame.Name, "resize", 'br:750:380', true);
}
Qva.Resize.Frame = true;
Qva.Select.Active = true;


}


function MaximiseMap() {


//x = document.body.innerHTML;
//document.body.innerText = x;

var MC = document.getElementById('MainContainer');
var MD = document.getElementById('mapdiv');

while (MD.parentNode != MC)
{
MD = MD.parentNode;

}
//alert(MD);


Qva.Resize.Frame = MD;
var objectMgr = Qva.Resize.Frame.AvqMgr;

if (objectMgr) { objectMgr.Set(Qva.Resize.Frame.ObjectId, "resize", 'br:750:480', true); }
else {
var binder = Qva.GetBinder(Qva.Resize.Frame.binderid); binder.Set (Qva.Resize.Frame.Name, "resize", 'br:750:480', true);
}
Qva.Resize.Frame = true;
Qva.Select.Active = true;
}

The problem is that when I press resize button in the report, the frame of the report is being maximised, instead I want the map to be resized with out maximising the frame of it.
Can any one help me regarding this.



Many Thanks
