Batch File "if" and "goto" problems - batch-file

Question

Whenever i run the .bat file it all goes well i choose my time it says it in minutes and all until it comes to confirming your decision and i really have no clue how to fix it for some reason it just goes to :shutdown
Intention: I am using this as a simple little tool when installing games for example if i have to leave steam to download and install a large game overnight i just choose a time and leave it :)
Note: I have no experience with coding ( except changing values on LUA scripts in games ) so an explanation would be
Greatly Appreciated and yes sure i can just use the shutdown command but i wanted to create something a little more fancy
Also if someone could explain to me what the
/s in shutdown
and /a in set timedelay commands do because as i stated i have little to no experience
.
If you can't answer or can't be bothered thank you for your time either way!
Thank you in advance! :)

if "%confirmaation%" == "2" goto choosedelay
if "%confirmaation%" == "3" goto exit
:shutdown

echo %timedelaysec% Seconds
echo ( %timedelaymin% Minutes )

:exit

ping 0.0.0.0 -n 2

:Temporary so it doesn't actually enable the shutdown
shutdown /s /t %timedelaysec%

Answer 1

In batch files, it's usually something simple and frustrating.
Try
set /p confirmaation=
(Note that I removed a space before the equals.)
If that fixes your problems, your environment variable wasn't set to any of the three values you checked for and the logic very naturally went line-by-line to :shutdown.
Good luck!
