BASH function: syntax error near unexpected token `'2'' - bash

Question

I am completely lost as to why this error keeps happening, I am fairly certain that I am using the correct syntax, however, every time I execute this BASH script, I get the following error:
/home/clucky/MCServerBackup/MCServerBackup.sh: line 200: syntax error near unexpected token `'2''
/home/clucky/MCServerBackup/MCServerBackup.sh: line 200: ` logInfo() '2' "none" "Minecraft: $minecraftsize.$minecraftsized $minecraftunit"'
The line in particular that it appears to be refrencing is line 200, which is where the code attempts to execute the function logInfo() as follows:
logInfo() '2' "none" "Minecraft: $minecraftsize.$minecraftsized $minecraftunit"
In the above line of code, 2 is the indent level (2 x 5 spaces). none tells the function to ignore the logLevel that is specified in the configuration and log it anyway. Minecraft: $minecraftsize...$minecraftunit is what is being added into the log file, which the words preceeded by a $ are of course variables. The entire code can be viewed below.
#! /usr/bin/env bash

As I stated earlier, I am completely lost, so any assistance would be greatly appreciated. Thank you!

Answer 1

You don't invoke a function with parentheses. Change:
logInfo() '2' "none" "Minecraft: $minecraftsize.$minecraftsized $minecraftunit"
to
logInfo '2' "none" "Minecraft: $minecraftsize.$minecraftsized $minecraftunit"
