How to get the value incremented only when the loop is true?

Question

Hi,
   From the snapshot attached, i want to increment the value of number indicator only once when its true and should increment the value again when the loop is true..i mean i want to get the number of times the loop is true.
But in this vi i am getting the value incremented many number of times when the loop is true because the while loop is running continuously.

A loop is a structure and not a boolean, so it cannot be false or true and thus I don't understand the question!
Why don't you attach the actual VI instead of a word document? Your code is very difficult to understand because it seems to suffer from severe localitis, and some of the few visible terminals don't show a label. What's in the other cases of the case structures?
Incrementing a value is better done in a shift register or feedback node. What's the purpose of the "absolute value" function. As long as you make sure you don't start with a negative value, it should not be needed. If you are looking for a off-on transition, try "implies" with the current and previous value of the boolean. (For an example, have a look at this post and the quoted example in it.)
