problem with Ant

I've been trying to run ant throught the command line but I get the following error message:

ANT_HOME is ser incorrectly or ant could not be located.

I have set ANT_HOME to the location where i unzipped the apache-ant-1.6.2 zip file(c:\ant)

I have also set the classpath to %ANT_HOME%\BIN and added %ANT_HOME%\bin to the path variable.

Can someone please tell me what the problem might be and how I could fix it.
