Can't find the problem. crosses initialization of 'std::ifstream inFile'

SigmundSeegrass (2)
I started learning C++ 2 days ago so sry if its messy.

As soon as i try to read from a txt file (Line 59)
the error: "crosses initialization of 'std::ifstream inFile'" occurs.

I commented the error messages to the according lines.

I know its alot of code but i cant figure it out myself.

System:
Win7 64bit, IDE: Code::Blocks 13.12



This "programm" will be able to save lists of values as txt files and load them back in.
After that it will choose and print one random value from the designated list to the console.
So basicly an advanced "roll the dice" thing.

move line 59 before the switch. Also, remember to close the file.
