[beginner] start button executing sub vi only once

[arvin1947]

Dear Friends,

I have for loop which is connected to an array and thanks to auto indexing I expect to execute it for the size of array and it only executes once.

Attached is my VI and wondering how can I run it more 

what makes it stop?

Please solve 1 problem before starting to work on another.

All 3 of your threads look like you are trying to apply the same overly complicated code to solve different problems

The problem is that you have not save any data your controls.  You start out with an empty 1-D array.  It has zero elements.  Then you build that into a 2-d array.  That gives you 1 row which is why your For Loop auto-index once.  But in reality, you have a 1 x 0 element array.

It seems like you still need to take some tutorials on LabVIEW.

I really appreciate your comment and link, but I think it would be better to give some hint to help me to get the solutions

I got your point now, I made 2d array with only one element, do you know any example that I can go through and learn auto indexing of array using for loop?
