Hi goker,

general hint for posting in this forum:

When you have problems with your VI you should post the VI (or atleast a picture of the block diagram, snippets preferred).

"I could not apply that with arrays 😕 comparison becomes borken arrow."

Comparison functions except arrays too. Please post your VI.
