script will not update the password

I am writing a script to deploy the automated bios upgrade the script runs fine until the point where it requires a password I have placed a statement in the script to add the password "REM if %script%== Biospassword goto main". The problem is that prompt for the password appears but it will not enter the password and continue with the installation. Help!
