A VBA Excel Loop Question??

I need to loop though a range of cells but I need to skip those cells that have an AVERAGE formula in them...

This is what I currently have:

VB Code:

Sheet1.Range("j6").Select
 
Do Until ActiveCell.Value = "N/A"
    Select Case ActiveCell.Value
        Case Is >= 70
            ActiveCell.Font.ColorIndex = 1
            ActiveCell.Interior.ColorIndex = 6
        Case 62.4 To 69.4
            ActiveCell.Font.ColorIndex = 1
            ActiveCell.Interior.ColorIndex = 44
        Case 54.4 To 62.4
            ActiveCell.Font.ColorIndex = 1
            ActiveCell.Interior.ColorIndex = 45
        Case 45.4 To 54.4
            ActiveCell.Font.ColorIndex = 1
            ActiveCell.Interior.ColorIndex = 46
        Case 37.4 To 45.4
            ActiveCell.Font.ColorIndex = 1
            ActiveCell.Interior.ColorIndex = 3
        Case Is = ""
            ActiveCell.Font.ColorIndex = 1
            ActiveCell.Interior.ColorIndex = 2
        Case Is <= 37
            ActiveCell.Font.ColorIndex = 2
            ActiveCell.Interior.ColorIndex = 1
 
    End Select
    
    ActiveCell.Offset(1, 0).Select
Loop
    Sheet1.Range("e4").Select

This will work fine in color codeing the cells that fall in a range, but in the range that I am looping through there are rows that are designated for averaging specific cells...For example - Cells A1:A3 are averaged at A4...then A6:A9 are averaged at A10.

The problem happens when there is no data in some of these cells that cause the AVERAGE to show -#DIV/0! this causes a Type Mismatch Error.

Can someone please assist me with figuring this out?

Thank you.
