Inserting a variable into a function

[Rayder44 0]

Hi all,
 
I hope this hasn't been covered before. I also hope it's not something insanely simple... Hopefully I get my terminology right.
 
So I'm running apiece of code which sets the injection rate for a fusion reactor, the line reads:

component.reactor_logic_adapter.setInjectionRate()

The method expects a number to be used in the brackets, which is fine. But I want to run some other code and use a number stored in a variable. I'm running some code to work out what injection rate I need. Ideally I'd like to run something like this:

local a = 2
component.reactor_logic_adapter.setInjectionRate(a)

But of course that doesn't work haha. Is there a way I can insert a variable like that?

Suprisingly, your second piece of code is totally valid, and is a way you pass the value of variable as an argument.

The error I'm getting is this:

/test.lua:11: ')' expected near 'a'

The only thing I can think of is for whatever reason, the method can't retrieve a variable like that. Is there anything else I can do?

 

The mod I'm using is Mekanism, for reference.

 

EDIT: Oh I done goofed! I was referencing the same variable in the next line in a print function. Seems I stuffed up the formatting there!

 

Thanks for your help!
