How do I use checkboxes in an IF-THEN statement in Excel VBA 2010?

Question

I need to use the value of checkboxes for an IF-THEN statement. Based on what the user checks, the way I have to calculate things changes. However, I can't figure out how to use the checkbox values, or how to detect them. Here is the code I have so far:

Private Sub Workbook_Open()
    Range("E1:F7,A1:A4,B1:B4,C1:C3").Select
    With Selection.Borders(xlEdgeLeft)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
    With Selection.Borders(xlEdgeTop)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
    With Selection.Borders(xlEdgeBottom)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
    With Selection.Borders(xlEdgeRight)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
    With Selection.Borders(xlInsideVertical)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
    With Selection.Borders(xlInsideHorizontal)
        .LineStyle = xlContinuous
        .ColorIndex = 0
        .TintAndShade = 0
        .Weight = xlThin
    End With
    Range("A1").Select
    Range("A1") = "Time"
    Range("B1") = "Specimen Shape"
    Range("C1") = "Data Type"
    Range("A1:C1").Font.Bold = True
    Range("E1") = "Owner"
    Range("E2") = "Experiment Date"
    Range("E3") = "Specimen ID"
    Range("E4") = "Contaminant"
    Range("E5") = "Leachant"
    Range("E6") = "Temperature"
    Range("E7") = "Regression Title"
    Range("E1:E7").Font.Bold = True
    Columns("A:E").EntireColumn.EntireColumn.Autofit
    'Formatting Column A
    Columns("A").EntireColumn.ColumnWidth = 9.71
    ActiveSheet.CheckBoxes.Add(4, 14.5, 72, 17.25).Select
    Selection.Characters.Text = "Days"
    Range("A6").Select
    ActiveSheet.CheckBoxes.Add(4, 30.5, 73.5, 17.25).Select
    Selection.Characters.Text = "Hours"
    ActiveSheet.CheckBoxes.Add(4, 45.75, 52.5, 17.25).Select
    Selection.Characters.Text = "Minutes"
    'Formatting Column B
    ActiveSheet.CheckBoxes.Add(58, 14.5, 72, 17.25).Select
    Selection.Characters.Text = "Cylinder"
    ActiveSheet.CheckBoxes.Add(58, 30.5, 73.5, 17.25).Select
    Selection.Characters.Text = "Wafer"
    ActiveSheet.CheckBoxes.Add(58, 45.75, 52.5, 17.25).Select
    Selection.Characters.Text = "Irregular"
    'Formatting Column C
    Columns("C").EntireColumn.ColumnWidth = 12.71
    ActiveSheet.CheckBoxes.Add(140.5, 14.5, 72, 17.25).Select
    Selection.Characters.Text = "Incremental"
    ActiveSheet.CheckBoxes.Add(140.5, 30.5, 72, 17.25).Select
    Selection.Characters.Text = "Cumulative"
    Columns("F").EntireColumn.ColumnWidth = 60
    Range("A1:C1").HorizontalAlignment = xlCenter
    Range("F1").Select
    Dim btn As Button
    Dim rng As Range
    With Worksheets("Sheet1")
        Set rng = .Range("A9:C9")
            Set btn = .Buttons.Add(rng.Left, rng.Top, rng.Width, rng.Height)
        With btn
            .Caption = "After making your selections above, click this button to continue."
            .AutoSize = True
            .OnAction = "DataInput"
        End With
    End With
End Sub

What I want it to do, just as a test, is if the "Time" checkbox is checked, and then the button is pressed to continue, I want it to say something like "YAY", using an IF-THEN statement. If the "Time" checkbox is not checked and you press continue, I'd like it to say "AWW...".

This is what I tried to make that happen, and it isn't working.

Sub DataInput()
    If ActiveSheet.Shapes.Range(Array("Check Box 1")).Value = True Then
    MsgBox ("Yay")
    Else: MsgBox ("Aww")
    End If
End Sub

What am I doing wrong?

If Sheets("Sheet1").OLEObjects("CheckBox1").Object.Value = True Then

I believe Tim is right. You have a Form Control. For that you have to use this

If ActiveSheet.Shapes("Check Box 1").ControlFormat.Value = 1 Then
