I am trying to insert a "re-order" link/ button on the Previous orders lists on 'My Account' and/ or 'Order history' pages.

I tried adapting the code form the order_history sidebox but cannot seem to get it to work. (Not sure if it would work anyway due to lack of enough PHP knowledge).

Has anyone been able to get a 're-order' working as either text or button?

I am not using sideboxes so I can't see what the order_history sidebox does.
