i want the background i have used on my iframe to stay at a constant position, i dont want it to move when i scroll downwards any suggestions?

ive noticed that in IE the method i have used works but for firefox it does not

all i did to make it work in IE was make the image a watermark

background-attachment: fixed;
Add that to the BODY section of your CSS of the page inside the iframe.
If that's what you have used please post your code/the page so we can see if there's any errors, that method should work in Firefox
