K2 Event not executing

Hi All,

I currently have a workflow that has an activity that starts on a dynamic datetime field.

The activity starts at the correct time, however the Event Code within the activity isn't being executed. I'm not too sure why it isn't being executed, there is an if statement within the code to check if field A == 'Y' then K2.ExpireActivity("Activity Name");

The activity name does exist within the workflow

Suggestions would be most appreciated

Thanks.
