I was trying to open a folder on every lab computer using a batch script. The computers are labeled 01,02,03-18. I didn't think there was a way to convert the number from 1 to 01 so I used an if statement. But I am getting an error that says `9 was unexpected at this time`

```
@echo off
setlocal enabledelayedexpansion
SET "z=0"
SET "n=9"
for /L %%x in (1,1,18) do (
  SET v=%%x
  IF %v% LEQ %n%
  (
    SET num=%z%%v%
  ) ELSE (
    SET num=%v%
  )
  start "" "\\lab-!num!\
  pause
)

```
