I have a batch file in which I need to use a variable inside a variable's name. In case that doesn't make sense, here's an example:

@echo off
set FirstVariable=1
set SecondVariable=2
set ThirdVariable=3
set /p choose=Which variable: 
rem On previous line, user would input First, Second, or Third.
rem The next line is where I am having difficulty.
set /a final=34 + %%choose%Variable%
echo final
pause>nul
exit

I need a sum of an integer and that.... thing.
Any advice?
