You can't connect an array to a scalar indicator. Clicking the run arrow gives you a description of the error.

You can also hover over the wire with Context Help (Ctrl-H) turned on.

p.s. Your code makes no sense. Why add the iteration count with zero?

This will get you started.  You have a lot more reading to do than just that, though.

the function of  this code is the cumulative of N which can be changed to your desired number

Hi there,

I guess you need to understand about the For Loop and the auto-indexing tunnel.

Here's the link: https://www.ni.com/docs/en-US/bundle/labview/page/processing-individual-elements-in-an-array-or-a-co...

But as billko suggested, try learning LabVIEW on that link that he posted, before going to this link.

This changes the cursor. Use this to click on your input tunnel:

 

This should then give you the answer you need:
