Beginner mistake probably involving functions.

[Βlasphemy]

Okay. So since I am learning Lua, and coding in general, I decided to try to make a simple script that uses pre-determined to follow a checklist, and then have everything assemble together with concatenation in a final sentence.

Here is my code:

age = 19
photoid = 1

function youAge(whatsAge)
end

function photoPossess(whatsPhoto)
end

function myWord(whatsWord)
end

if age == 20 then
	youAge("You are 20 ")
else
	youAge("You are not 20 ")
end

if photoid == 1 then
	photoPossess("you can buy alcohol.")
else
	photoPossess ("you can not buy alcohol.")
end

if age == 20 and photoid == 1 then
	myWord("and ")
else
	myWord("but ")
end

function alcoholics()
	Msg(whatsAge..whatsWord..whatsPhoto) --Here is where console is saying the wrench is stuck.
end

alcoholics()

The error in Gmod is claiming this.

[lua\alcoholics.lua:33] attempt to concatenate global 'whatsWord' (a nil value)

Now, I think I must have messed something up with the functions in the if/then statements, because the console looks like it is saying to me in console that whatsWord is a function instead of an argument like I assigned earlier in the code. whatsWord being the argument belonging to the function myWord() ( myWord(whatsWord) ).

If you can tell me what the problem is, and why it is happening, that would be greatly appreciated. Also, if you have any ideas on how to optimize the code, that would help too. Thanks for reading!

You never defined whatsWord, whatsAge, and whatsPhoto.

You cannot call a argument of a function, only the function.

The argument passed into a function is dynamic either way.
