array out of range with Indicator

[Dan]

Hey folks,

I simply wanna do the following thing:

if the bollinger bands (upper and lower band) spread out, there should be an arrow on the upper and lower Band be drawn.

For the upper band is it working, but for the lower band I'll get the array out of range error.

May one specialist here can teach me right.

Big thanks in advance!
