Why Doesn't this Seem to Work?

[TKithin01]

Left Stick UP`Left Y+` & ! `Shoulder L`) | (`Left Y-` & `Shoulder L`) ^ (`Left Y+` & ! `Shoulder R`) | (`Left Y-` & `Shoulder R`)
Left Stick Down: (`Left Y-` & ! `Shoulder L`) | (`Left Y+` & `Shoulder L`) ^ (`Left Y-` & ! `Shoulder R`) | (`Left Y+` & `Shoulder R`)

or

Left Stick UP`Left Y+` & ! `Shoulder L`) | (`Left Y-` & `Shoulder L`) | (`Left Y+` & ! `Shoulder R`) | (`Left Y-` & `Shoulder R`)
Left Stick Down: (`Left Y-` & ! `Shoulder L`) | (`Left Y+` & `Shoulder L`) | (`Left Y-` & ! `Shoulder R`) | (`Left Y+` & `Shoulder R`)

But Neither of Those Seem to Allow Any Vertical Stick Movement with Either Left or Right Held

I've also Written it this way:

Left Stick UP: (`Left Y+` & ! `Shoulder L` ^ `Shoulder R`) | (`Left Y-` & `Shoulder L` ^ `Shoulder R`)
Left Stick Down: (`Left Y-` & ! `Shoulder L` ^ `Shoulder R`) | (`Left Y+` & `Shoulder L` ^ `Shoulder R`)

Which Lets the Left Shoulder Button Work but No Movement when Right is Pressed...

Left Stick UP: (`Left Y+` & ! `Shoulder L` ^ `Shoulder R`) ^ (`Left Y-` & `Shoulder L` ^ `Shoulder R`)
Left Stick Down: (`Left Y-` & ! `Shoulder L` ^ `Shoulder R`) ^ (`Left Y+` & `Shoulder L` ^ `Shoulder R`)

Writing it this way Lets Left Shoulder Work as Intended but it treats Right Shoulder like Its not Even Pressed or is Still Normal

Left Stick UP: (`Left Y+` & ! `Shoulder L` | `Shoulder R`) ^ (`Left Y-` & `Shoulder L` | `Shoulder R`)
Left Stick Down: (`Left Y-` & ! `Shoulder L` | `Shoulder R`) ^ (`Left Y+` & `Shoulder L` | `Shoulder R`)

This Breaks the Vertical Movement with Right Shoulder Held
