I have a function that works on PC but not on Android.

function chatter.send()
bunch of code
end

when chatter.send() is called on Android it has the error: attempt to call field 'send' (a nil value)

but on PC (Linux) it works perfect

Thoughts?

Strange. No idea why it would be different.
What type is chatter, a simple table?

It sets a timer and when the timer completes it sends a message to chat. It's what the shops use to broadcast their messages.
