No, ValueWhen returns a whole array. If you only want the most-recent
value, use the LastValue function. Otherwise you need to decide which
value (ie. from which bar) you want to pass to the function, which
will depend on what the function is doing.

there a way I can pass the array value(just a single number) to the
function input. I tried valuewhen and it doesn't like that as well.
