ValueWhen()  function is used to get value of the array when condition met

SYNTAX   	ValueWhen(EXPRESSION, ARRAY, n = 1)

and check the below given afl for fibonacci levels

So according to this code and my requirment
should it be like this valuewhen(Cross(high,fib3),High,nth=3);
here nth=3 means when high crosed 3rd time fib3 it will give me signal or will give me that high …ryt sir?
