Issue with threads, timer, and label

Hi, I'm having an issue with this code that I'm writing, I'm curious as
to why the windows form label (lblTime) isn't getting updated with the
new variable when I use the timer. I made a blank form with only the
timer and the label, and it works fine, is there something else I need
to do with the threads to get this to work? I'm a bit lost here.

Thanks in advance -- Aaryn
