Array To Check User Input Match

This is what i want to do: SEE ATTACHEMENT

•Write codes to pop up an InputBox to ask the user for a customer name.

•The program uses the user’s input to check whether the name is on the list. If it is, display an msgbox saying that the customer name is on the list, and the corresponding cell will be indicated in boldface and in blue. Otherwise, an msgbox will be displayed saying that the customer name is not on the list.

Dim the customer list as an array (string var. type) and Dim Found as Boolean. You will need the If-Then construction and For-Next or Do-While/Until loop too). Create a button to run and another to restore the formatting to its original style.

This is what i did so far and still having problems with it:

Option Explicit

Sub customers()

Dim Arr()
Dim R As Integer
Dim C As Integer
Dim ReturnColumn As Boolean
