WOW that worked!!
Please forgive my ignorance, but what does that extra "." do? I'm aware that "." signifies your current directory.
If you don't want to explain fully and have a good reference for me to read I'm VERY open to that.
Thanks for all of your help again!!!

running a script with

Code:
. filename [arguments]

does "source" the filename, thus all environment changes within subprocess running filename became reflected into the parent, or current environment.

Very often I'd use this technique when .profiel is changed, then I'd run

Code:
. ./.profile

and all the changes in the environment became current in my session.

With . filename [arguments] (or source filename [arguments]) you read and execute commands from filename in the current shell environment
so that cd affects your current shell, otherwise the script is executed in a subshell and the parent shell environment remains unaffected.

Thanks a TON, that makes perfect sense to me!
