Input Box and Msg box Help

Hi All,
I am trying to write a macro that involves and inputbox and msgbox. Here is what I am trying to do:

1. Inputbox to ask user to enter initials (Would like this to be a 2 character alpha only) with the OK/Cancel buttons option

----- a. If the user selects CANCEL then EXIT SUB


2. If the user selects OK and

------ a. the criteria (2 character alpha) OR
------ b. input is blank, Then

---------- I. Msgbox with message “you must enter a valid 2 character initial” with the retry/cancel buttons option

With the msgbox present:

3. If user selects CANCEL then EXIT SUB

4. If user selects RETRY, loop back to step 1 above until,
----- a. User inputs valid initials Or
----- b. User selects the Cancel button option

5. If/when the user enters a valid initial, I would like to jump to a section of the code and run the remainder of the macro.


As long as the user selects RETRY, it will continue to loop starting at STEP 1 above.

Below is the code I have so far. I don't think that I am even close. Any help would be appreciated.

Thanks!

Code:

---

Dim Initials As String
Dim IR As VbMsgBoxResult
Dim MB As VbMsgBoxResult

Retry:

Initials = InputBox("Please Enter Your Initials for Sign Off", "Enter initials", vbOKCancel)
If Initials = vbCancel Then GoTo ExitAll

    ElseIf GoTo Proceed

Proceed:
    If Len(Initials) = 0 Then
          MsgBox "YOU MUST ENTER A VALID 2 CHARACTER INITIAL", vbRetryCancel, "Invalid Initials"

If vbRetry = 4 Then GoTo retry
If vbCancel = 2 Then

ExitAll:

Exit Sub

End If

End If

MainCode:

MY MACRO BELOW

End Sub

I usually do something like this

Code:

---

Option Explicit

Sub demo()
    Dim sInitials As Variant
    Dim bGoodInput As Boolean

    bGoodInput = False

    Do While Not bGoodInput
   
        sInitials = Application.InputBox("Enter TWO initials !!!", "Demo", vbNullString, , , , , 2)
        If sInitials = False Then Exit Sub
        If Len(sInitials) <> 2 Then
            If MsgBox("You must enter a valid 2 character initial", vbCritical + vbRetryCancel, "Demo") = vbCancel Then Exit Sub
        Else
            bGoodInput = True
        End If
    Loop

    MsgBox "run the rest"

End Sub
