Match Pattern Algorithm vi - No returned score when failed

[uoi]

Hi, 

I'm building a vi to do the pattern matching comparison between source image and template image.

However, there is no values, including score being returned Matches & Calibrated Matches indicators when the comparison fails.

With the passed results, the score value is returned in the both indicators.

I will need to the score to do some fine tuning when there is a failure.

So kindly need the advise from the expert to address this problem

Thanks.
