And this is why I was snide in my response, I should have stepped back and been more tactful. But it is SUCH bad advice I wouldn't want the newbe to think it is gospel and I didn't want to wait a minute just in case someone came along and tried it.
And again I am sorry I was such a smart ars, know me for a while and you will see I can be one often, but come back to my senses.
