Don't sweat it, if you need help just ask ;).

Although, there's not really any way to answer this. There's no current problem and it's just an assumption of something "possibly" missing. I can't know your entire database off 3 screenshots (or 20). Everything appears OK on those 3 screenshots. If this is a direct copy of something Richard has built, then re-watch the video to see if something is missing.

I would advise just move forward, if you run into a problem, then come back here. Don't be afraid to ask for help if you're having problems. As long as there is a problem I can wrap my head around I'd be glad to try to help ;).

Adam or Richard, this Database is based on the Invoicing Database that Richard showed us how to do a while back, I hope so anyway. My only concern is how wide the Details form needs to be to collect my required information. Using a Continuous form, I am not sure how else to do it. The 3 screenshots are the Database. A Customer Table, a Details Table and a Details Form. I still have the Form named Form until I decide on a more appropriate name. I have spent hours and hours watching and rewatching both through my cources I have taken and on youtube trying to learn how to do this and other Databases, and even then, I still find myself stumped sometimes. A.D.D. doesn't help either.
Thank you for your support and guidence.

If your concern is the width... just make it smaller.  You could change some of the words like Invoice Number to Invoice and shrink up the boxes. You could also just put the labels into the form header above the fields and save a ton of space.
