Can not catch the number of label

I set 2 labels,

one is at the queue (called "start_time")

and the other is at the sink(called "end_time")

I know the problem is I can't catch the number of the "end_time"

But I am sure the code is right...

thx~

Your model it catching the end_time just fine. The problem is that your labels (start_time and end_time) are equal (see attached model). When label start_time is printed when written to in the queue and when the label end_time is written to in the sink are displayed (in attached model) they are the same value. That seems to be where you problem is.

I find the problem....

I didn't give the code "return" of the process time of the MultiProcessor.

So.........It doesn't work........

Thx everyone!
