Global variables can remain defined as you edit if you remove the declaration. So it could be working locally but then break when you post it. Missing a declaration of m :)

It's a bug :|

Waaaaait, nevermind. It gets initialized when I hover my mouse over the dweet. I was a bit too quick there.
u/Galaxtone

Yah, I do that all the time
u/Galaxtone

Plus I already did that with a and b
u/Galaxtone

I just deleted it and fixed it
u/Galaxtone

So yah:

Ignore the m is undefined error, Just move your mouse inside the dwit to make it go away.

why do you assign m=e and don't simply use e
