So I have come up with this one. What do I have to change?

```
@echo off 
:U 
echo ****************** Time Converter!  ****************** 
set /p HOUR= Please Enter the Hours: 
set /p MIN= Plese Enter the Minutes:

if %hr% geq 12 (Set timeofday=pm) else (Set timeofday=am) 
if %hr% equ 0 (set /a HOUR=%HOUR%+12) 
if %hr% gtr 0 (set /a HOUR=%HOUR%) 
if %hr% gtr 12 (set /a HOUR=%HOUR%-12)

echo The time in 12hours is %HOUR%:%MIN%%timeofday%

```
