IF not condition

Hi All

when run Menu.bat file, it asks about select the option? options are as follows

1 Generate report staff
2 Generate report subjects
3 Generate report class
4 exit

My requirment is that when user enter incorrect option(i.e. not between 1 and 4) , I want to display message something like "you entered incorrect opntion, try again".

Thank You
