Caliper returns null values

[polymer]

Hi all,
Actually, I want to measure the diameter (using clamp tool) the object in the image, for that I have generated this VI (NIVA_bulid .vi) through NI vision assistant, where I can get the distance between the points 1 & 2 from caliper tool.
But , when I run as vi (derived from VisionScript.scr), the indicators Calibrated results and Caliper results shows only the zero value.
Can anybody please tell me what’s the problem in this? Looking forward for your eagerly.

Thanks.

The "Edge coordinates" output of the IMAQ Clamp Horizontal" vi should be wired to the "Points in" input of the "Caliper" vi.

See the attached vi. It's just a chunk of your original vi (I have some problems to post file larger than 20Ko...)

Hi Charly,
It's excellent, I have corrected the vi as you said, now it works perfectly.
But couldn't open your modified .vi since it's in Labview 7.1, I have only Labview 7.0. Is there any way to open higher version(7.1) .vi in lower one(7.0) ?

Anyway, I thank very much for your valuable help.


Thanks and Regards,
Prasath.
