Having trouble with nested IF in a batch file [duplicate]

I am making a batch file for checking out a project from SVN. I ask the user to enter the directory and when you reach the directory you want, you type checkout and it checks out that project directory. However, I am having some trouble with the code below. Please help.

if /i %choice%==1  ( 
cls
svn ls %svnroot_temp%
:top
set /p direct=Enter directory:
if %direct%=checkout( goto :checkout_area )
set svnroot_temp= %svnroot_temp%/%direct%
svn ls %svnroot_temp%
goto :top
)

Where am I going wrong here?

Never use :label nor :: label-like comment inside a command block enclosed in () parentheses. Proof:

@ECHO %1>NUL
if "" == "" (
    @echo a simple echo, no comments
)
if ""=="" (
  @echo a rem comment follows this echo command
  rem comment
  @echo a rem comment precedes this echo command
)
if ""=="" (
  @echo a label-like comment follows this echo command
  :: comment
  @echo a label-like comment precedes this echo command
)
if ""=="" (
  @echo a label follows this echo command
  :label
  @echo a label precedes this echo command
)

Output:

==>D:\bat\labels.bat OFF
a simple echo, no comments
a rem comment follows this echo command
a rem comment precedes this echo command
a label-like comment follows this echo command
'@echo' is not recognized as an internal or external command,
operable program or batch file.
a label follows this echo command
'@echo' is not recognized as an internal or external command,

Next code snippet should work as expected, if I can understand your aim:

SETLOCAL enableextensions

rem (set `svnroot_temp` and `choice` variables here)

if /i "%choice%"=="1"  ( 
    cls
    svn ls %svnroot_temp%
    call :top
)
goto :eof

:top
set /p direct=Enter directory:
if /I "%direct%"=="checkout" goto :checkout_area
set "svnroot_temp=%svnroot_temp%\%direct%"
svn ls %svnroot_temp%
goto :top

:checkout_area

Note that both compared expressions in if /I "%direct%"=="checkout" goto :checkout_area are enclosed in double quotes as any user input could contain a space or even could stay empty.
Not sure about quoting in svn ls "%svnroot_temp%".

Not sure whether "%svnroot_temp%" is an input or output directory for svn ls command:

• in case input: check it using if not exist "%svnroot_temp%\%direct%\" goto :top before changing it by set "svnroot_temp=%svnroot_temp%\%direct%"
• in case output: create it using MD "%svnroot_temp%" 2>NUL after changing it.
