I've gone through the search box HTML code provided by thehut.com line by line and can't seem to find any affiliate code in it. The only reference to any affiliate code is in the 1x1 pixel, but I can't imagine that would be used to register sales generated via the search box would it?

Was wondering if somebody else could dig out the affiliate code. I have changed <> to {} because otherwise doesn't show:

Extremely concerned, because after a few months the 3 month and 7 day EPC are 'N/A' for this particular link, even though there is a reasonable EPC for other thehut.com links. Also, just discovered that we haven't generated a single sale via the search box massive exposure.

Thanks very much
