How to create a vi for following requirement

[GerdW]

Hi ramkis,

your vi is working! No error before and after run...

It's not giving you the desired result, but that's not the problem of the VI

[ramkis]

Well, first, where's your timing.  You also have a loop with uninitialized shift registers which can give you undesired results (I hope I didn't say too much).

I don't know what you hope to accomplish with this code.  Your indicator will display only the result of the last iteration.

Your initial VI: What's the purpose of the shift register?  Start there.  The best way to learn is by doing.  These are very basic questions.
