Hello,
My site works perfectly in Google Chrome, but can't figure out why this doesn't work in Internet Explorer.

Try using the "Add to Cart" button doesn't work in Internet Explorer:

Here is the code I am using:
<FORM METHOD="LINK" ACTION="http://www.ccnow.com/cgi-local/cart.cgi?ldonkle_ROCKS_http://www.shirtattic.com"> <INPUT TYPE="submit" VALUE="Add to Cart"> </FORM>

It's like the url ignores everything after the question mark? Just copying the full link into Internet Explorer seems to work fine. ...so the problem must be with the button?

We replaced the button with a "add to cart" image. Never could figure out why the other button doesn't work. If someone can figure it out it would be greatly appreciated.

Is that all you changed?
