I'm sure this is easy, so dont point and laugh. But i'm getting aggravated at this little problem i'm having.
When i debug my batch file a error shows that "goto was unexpected at this time" right here:

if not %test%==%name% goto create

why in the world is this happening???, i've changed it around so the variables had quotes, or a space in between the equal signs, i've even tried taking the goto command of it and placing it underneath. I'm desperate.

Strange,

It works for me in this program; perhaps there's something more subtle going on in your own program. Could you post it?

@echo off
set test=Hi
set name=NotHi

if not %test%==%name% goto create

goto finish

:create
echo Hello

:finish
echo finishing.


When I run this, I get:

Hello
finishing.

Implying that it did go to the :create label.

This is where my problem is (******)

echo off
set comm=
cls
:begin
set /p name=Select User Name:
findstr "%name%" namelog.txt > nametmp.txt
set test=
for /f "tokens=1 delims= " %%a in ('type nametmp.txt') do CALL :process %%~a
if not %test%==%name% goto create    ****** ****** ****** ****** ****** ******
goto prob
:create
echo %name% >> namelog.txt
echo %name% was added succesfully to the LOG file
set /p comm=Create a new one? Y or N
if %comm%==Y goto begin
goto exit
:process
set test=%~1
echo I'm here
pause
goto EOF
:prob
echo The Username entered is already in use.
pause
:exit
cls
:EOF

I've been thinking that the call command above it might have had something to do with it. Cause when i debug this it acts like it dosen't go to :process at all before it reaches the if command.
I'm not sure, i'm speculating about everything, because i'm so confused about it.

It looks as though if you enter a name that doesn't exist, then the "test" variable is never set to anything, since it never calls the process procedure, which set the variable; being set to null appears to be confusing the statement that's having the problem.

As a test, I set it to something and this seems to solve the problem.

set test=XXXXXXXX

To tidy this up, you can use "if not defined" to check if the variable has been set up, rather than setting it to nothing to start with; so:

findstr "%name%" namelog.txt > nametmp.txt
for /f "tokens=1 delims= " %%a in ('type nametmp.txt') do CALL :process %%~a
if not defined %test% goto create
if not %test%==%name% goto create

This didn't do anything. I typed it in and now instead of just the goto error, it now says that create is not a internal or external command for the if not defined. I'm running XP Pro in case you need to know.

Apologies, made a typo: it's just:

if not defined test goto create

echo off
set comm=
cls
:begin
set /p name=Select User Name:
findstr "%name%" namelog.txt > nametmp.txt
for /f "tokens=1 delims= " %%a in ('type nametmp.txt') do CALL :process %%~a
if not defined test goto create
if not %test%==%name% goto create
goto prob
:create
echo Got to the create
echo %name% >> namelog.txt
echo %name% was added succesfully to the LOG file
set /p comm=Create a new one? Y or N
if %comm%==Y goto begin
goto exit
:process
echo Processing
set test=%~1
echo I'm here
pause
goto EOF
:prob
echo The Username entered is already in use.
pause
:exit
cls
:EOF
