Hi @AMIT KUMAR,

The error is because of a missing parentheses pair (the part in italics become separate completely leading to the error) -

B ( ( ( n - 1 ) / 3 ) + 1 ) : (2 * (n - 1) / 3 ) = 8

1 2 3 3 2 1

Adding an extra pair of parentheses '(.)' solves the error:

B( (((n-1)/3)+1):(2*(n-1)/3) )=8

Thanks.
