Need help with the chem sprayer

I'm trying to make a chemical sprayer but it doesn't shoot the custom spray I made for it. I get damage, yes. It's the case of the INVISIBLE SPRAY!

See anything wrong?

Try putting spry in all-caps.

It works...
Great now I look like a total n00b.

(Not that I already am, of course.)
