Ahhh, sorry about that, my mistake... I was thinking of another mod... Was working on about three things at the same time last night and it was getting late here.... Sorry, ignore what I said as it applied to Empty Cart Manager Mod which I'd been working on simultaneously.

I am using version 1-25 of FEC though.... which worked first time with no real issues. I can send you the files if required?

Has you button stopped working since you installed this mod? Are you certain that it's this mod install which affected the button?

If you switch to the default ZC template temporarily to check it, does the button re-activate?
