How to write a custom Excel 2016 function that gets first two characters of cell if numbers?

Grab First Two Numbers
If the cell's first three characters are 01-, I want them to be picked up.
If the cell is blank, I want the function to show 00-.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this
=IF(ISBLANK(B9),"00-",LEFT(B9,3))&IF(ISBLANK(C9),"00-",LEFT(C9,3))&IF(ISBLANK(D9),"00",LEFT(C9,2))

Sorry, I forgot to include Custom with function in the question.

Then you can use this

Function CombineText(rg As Range) As String
    Dim col As Integer
    If rg.Columns.Count = 3 And rg.Rows.Count = 1 Then
        For col = 1 To 3
            If rg.Cells(1, col) = "" Then
                CombineText = CombineText & "00"
            Else
                CombineText = CombineText & Left(rg.Cells(1, 1), 2)
            End If
            If col < 3 Then
                CombineText = CombineText & "-"
            End If
        Next col
    End If
End Function

I tried out the function, but when the 2nd column changed, the function didn't update.

Sorry, typing error.
Use this
Function CombineText(rg As Range) As String
    Dim col As Integer
    If rg.Columns.Count = 3 And rg.Rows.Count = 1 Then
        For col = 1 To 3
            If rg.Cells(1, col) = "" Then
                CombineText = CombineText & "00"
            Else
                CombineText = CombineText & Left(rg.Cells(1, col), 2)
            End If
            If col < 3 Then
                CombineText = CombineText & "-"
            End If
