Hello, I'm Chris. Thanks for seeking us for help.
It may take me 1-2-3-etc... responses to get the information I need resulting in giving you the answer you need. I can't read minds nor have a magic wand, & I'm not there to see, smell, feel, or hear so I need good information to return a good answer. My normal hours online are 3pm-3am.
