First what I am trying to do:

I have zen cart as part of a wider site. I am trying to link into the contact_us page of the store from outside zen cart. The link works fine but once I am there the back button on the contact_us page sulks and won't play the game.

Is there a nice solution out there already for this? I can't find one on the forum.

So, where is zen_back_link() defined. I can't seem to find that either. I kind of thought it would be in includes/functions?

Any advice?

Thanks guys
