Boolean control reference

[Ya-hoo]

I creat a boolean reference to pass the boolean value to a subvi. When the button in main vi is pressed, the refnum in main vi not changed, but the refnum passed to subvi changed to 0. So TRUE or FALSE value never passed to subvi. I tried it in a small program which has same structure with this one, and it works fine. Any idea?

Thx.

OK, I found a trick in my program. Now it is all fine.
Thx.
