User Variable For Each Market Problem

Hi,
I have been having a problem with a trigger. A user variable I have is defined as "Individually for each market"to contain a value specific to a specific market, but it seems that when another market becomes active it adds to the user variable as though it was global.
I have mocked up a simple trigger to show what I mean, the reset user variable activates on 20 mins before off then any active markets add 1 to total every 60 seconds. Can anyone explain where I'm going wrong

Remove the global initialization of the variable (at the top).

Thanks Tim, barking up the correct tree now.
