Little adjustment needed for an alert function indicator

Hi, I got a little tool indicator that works as a pitchfork on the last 240bars, it has an alert function in it that can be switched on and off.
But the off 'false' doesn't work and the alert pops off each time i change the tf, so it's kinda like drivin me crazy..
I really don't know how to make it work the way it should, doesn't seem a biggy for someone who's into coding..
Thank you,
here it is
