internet explorer and mozilla

[jesmi]

following is my code for the image position. it works nicely in internet explorer. but it doesn't support for mozilla. In mozilla, the image position is in the random places than i have directed. here's my code:

function my_DropFunc()
{
dd.obj.copies[0].hide();

if(dd.obj.x >25 && dd.obj.x <150 && dd.obj.y <450){
dd.obj.moveTo(52,296);
dd.obj.resizeTo(400,152);

document.myForm.template1.value = test;
document.myForm.X1.value = dd.obj.x;
document.myForm.Y1.value = dd.obj.y;


}
else if(dd.obj.x <150){
document.myForm.template1.value = "";
document.myForm.X1.value = "";
document.myForm.Y1.value = "";

dd.obj.moveTo(50,480);
dd.obj.resizeTo(92,118);
}

if(dd.obj.x >150 && dd.obj.y <450){
dd.obj.moveTo(268,131);
dd.obj.resizeTo(185,150);

document.myForm.template2.value = test1;
document.myForm.X2.value = dd.obj.x;
document.myForm.Y2.value = dd.obj.y;

}
else if(dd.obj.x >150 ){
document.myForm.template2.value = "";
document.myForm.X2.value = "";
document.myForm.Y2.value = "";

dd.obj.moveTo(160,480);
dd.obj.resizeTo(92,118);
}


}

please help me to solve above problem.

thanks in advance

If this is truly a html/css problem, then we need to see the generated html and css.
