document.getElementById("imgAttach").click(); Access is denied

Question

I am getting Access is denied in IE

I have a hidden button which i click after another button is clicked:

button clicked calls:

document.getElementById("imgAttach").click();

And in IE i get an access error. How do i fix this?

The button i'm trying to invoke a click on:

<input type="image" name="imgAttach" id="imgAttach" src="ICCMImages/Paperclip.PNG" style="border-width:0px;float:right; visibility:hidden" />
