Confusion with Batch-file code -

-

so started learning batch-file, , today decided try , make game it. have few errors, , can't figure out wrong code. heres code:

@echo off title batch rpg color 07  echo welcome batch rpg! echo. echo. pause  :menu cls echo. echo    -menu- echo. echo. echo. echo    1) begin echo. echo    2) how play echo. echo    3) exit echo. echo. echo. echo    --------- echo.     set /p c=choice:          if %c%==1 goto prestart1         if %c%==2 goto howtoplay         if %c%==3 goto cfr_exit         if not %c%==1 if not %c%==2 if not %c%==3 goto menu   :cfr_exit cls echo. echo    sure want exit? echo.     set /p c=(y/n):          if %c%=="y" exit         if %c%=="n" goto menu         if not %c%=="y" if not %c%=="n" goto cfr_exit2  :cfr_exit2 cls echo. echo    must enter valid option. echo. pause goto cfr_exit  :howtoplay cls echo. echo    -how play- echo. echo. echo. echo    game simple. there number option after it, type option in , perform action(as option say). echo. pause goto menu  :prestart1 cls echo. echo    welcome land of fageryth! echo. echo    name, adventurer? echo.     set /p playername=name:  goto prestart2  :prestart2 cls echo. echo    more valued statistic, attack damage, or hit points? echo. echo. echo. echo    1)attack damage(atk) echo. echo    2)hit points(hp) echo. echo. echo. echo    --------- echo.     set /p playermorevaluedstat=choice:          if %playermorevaluedstat%==1             set playeratk=6             set playerhp=25         if %playermorevaluedstat%==2              set playeratk=4             set playerhp=30         if not %playermorevaluedstat%==1 if not %playermorevaluedstat%==2 goto prestart2 cls echo playeratk echo playerhp pause

i'm having trouble :prestart2 section of code. end of it, tried make if variable wasn't equal 1 or 2, options, send player start of section again, , also, when finishes checking, i'm trying make display 2 variables playeratk , playerhp instead closes out. lost here , appreciate help!

a couple things before start:

first, when troubleshooting batch scripts, rid of (comment out) echo off , cls lines can see it's going wrong.

second, should double-quote variables make sure you're not inadvertently including spaces when setting , comparing them. doesn't seem causing problems in code, it's habit into: 

set "var1=something" set "var2=a string spaces" if "%var1%"=="something" echo %var1%

now, problem in code 2 if statements stretching on multiple lines. if you're going that, have put them inside of parentheses.

set /p playermorevaluedstat=choice:          if %playermorevaluedstat%==1 (             set playeratk=6             set playerhp=25             )         if %playermorevaluedstat%==2 (             set playeratk=4             set playerhp=30             )
