A little help?

I've been goign through and changing a few values in my scripts, mostly just screwing around and pissing others off.

But I got an idea to turn the tesla cannon into a super weapon. First i thought I would add an alternate fire by giving it flamer unit ammo, but that didn't work, so I figured "Well duh the flamer unit is a primary ammo type!" So i changed the alt fire to incendiary grenades. But alas, to no avail.

I'm kind of at a loss here. Is what I'm trying to do even possible? Below is my Tesla file.
