1 of 2 userforms not working due to change event

I have an incomplete project I have been working on and do not want to move on until I get this problem resolved (little things like this bug me). Perhaps I just need a second pair of eyes. However, the problem that I am having is that I am using a userform to update cells in a sheet. I have 2 userforms that are very similar and one works and the other does not. The suppliers editing part of the program is working just fine. It updates as expected. The customers userform will only update the first name in the sheet; the other fields remain unchanged and refresh as the same while no changes are made in the sheet. I pretty much copied and pasted the code from the suppliers over to the customers and made all of the appropriate changes that I found. I have looked over it for hours on end and just cannot figure out why all of the information in the customers cannot be updated.

On a side note, while I was cleaning out most of the records from the sheet I got errors when I cleaned all of the records out, I have no clue how to handle these errors when there is no information in the sheets for the userforms to pull up. This error is not as pressing to me since the sheet will never be empty when in use, but it still bothers me knowing its there and not handled.

Thank you ahead of time for any help and sorry for the long first post, its 4 am. so it is possible I have rambled
