Calling Functions
 

What I write below works. I am trying to figure out why

in the Lua
function ExecuteWarning_Update(name, health, maxhealth)

When I go back to the xml

I see the button has an on load script
this:RegisterEvent("UNIT_HEALTH"); this:RegisterEvent("UNIT_MAXHEALTH"); this:RegisterEvent("UNIT_NAME_UPDATE");

with on_event
ExecuteWarning_Update();

How much wiggle room is there or are there some variable definitions that I missed somewhere?

Hmm, I am guessing that functions can have parameters as long as they are not called with parameters if they don't exist in reality. *shrugs* Just a guess mind you.
