Range Question

I have a Range E9:E17 that I would like to look at one cell at a time. I figured I would use this code to do that. My first question is how would I put the value of each of those cells into something like Part I have below without a mismatch?
Second Question how do I handle it if someone adds a row to the spreadsheet?

Sub test()

Dim Part as string

Dim rngCell As Range
For Each rngCell In Range("e9:e17")
  'what you want to do with the cell
Next rngCell






End Sub
