makes perfect sense, thank you ,you are right over thinking just does not work.I knew the conversion was thinking they wanted more lol obviously not. I have been doing conversions I was making it harder that what it was.I start school monday I am an over achiever which is why I should wait to make it easier on myself.

Thank you everyone for correcting me .
