problem with midi notes

hello,

I am using max/msp for quite some time now but have never used it before with inserting midi notes. However I am trying to make this legato thing that this guy here has made for a tb 303 tutorial

Does anyone know why my toggle doesn’t turn on/off?

Any help would be useful,
thanks
