Calling a member function using text to specify function name

[Colm Sloan <colmsloan@...>]

I'm trying to call a function, let's say it's called:

MyClass:MyFunction01

I'm trying to pass the name of the function as text where it can be later called. Here's what I've tried:

local functionName = 'MyClass.MyFunction01'

_G[ functionName ]()

This method was taken from here ( http://stackoverflow.com/questions/1791234/lua-call-function-from-a-string-with-function-name ).

 I get the error:

"attempt to call field 'CLua_NPC_Nurse.PrintTest' (a nil value)"

I looked in the _G table and found that it does have the entry for my class and I'm sure my class has that function. Could anyone tell me what I'm doing wrong and how I can fix it?

Thanks :)
