Select View Toolbars Control Toolbox to display the Control Toolbox
toolbar. Add a check box to your worksheet. Right-click on the checkbox and
select View Code. The Visual Basic Editor (VBE) is displayed with an empty
subroutine for the Click event for the checkbox. Probably the following:

Private Sub CheckBox1_Click()
End Sub

Paste the following code in the subroutine (between those two lines):

Range("A3:C3").Select
If CheckBox1.Value = True Then
With Selection.Interior
.ColorIndex = 6
.Pattern = xlSolid
End With
Selection.Font.ColorIndex = 6
With Selection.Borders(xlEdgeLeft)
.ColorIndex = 6
End With
With Selection.Borders(xlEdgeTop)
.ColorIndex = 6
End With
With Selection.Borders(xlEdgeBottom)
.ColorIndex = 6
End With
With Selection.Borders(xlEdgeRight)
.ColorIndex = 6
End With
Else
With Selection.Interior
.ColorIndex = xlAutomatic
.Pattern = xlSolid
End With
Selection.Font.ColorIndex = xlAutomatic
With Selection.Borders(xlEdgeLeft)
.ColorIndex = xlAutomatic
End With
With Selection.Borders(xlEdgeTop)
.ColorIndex = xlAutomatic
End With
With Selection.Borders(xlEdgeBottom)
.ColorIndex = xlAutomatic
End With
With Selection.Borders(xlEdgeRight)
.ColorIndex = xlAutomatic
End With
End If

This is basically code I recorded with the macro recorder. It will color the
merged cells' font, background, and borders yellow when the checkbox is
checked. Unchecking the checkbox restores the cells to the default black on
white colors.

Save the workbook, then select File Close (in the VBE) to return to
regular Excel. Click the 'Exit Design Mode' button on the Control Toolbox
toolbar (probably the first button), and try out your new checkbox.

I am trying to make checkbox1 change font color, background color and
add/remove border lines if possible.

I am really not sure how to write the code for this at all. I would like to
change the font from black to yellow, and the background color in cell A3,
B3, C3 (one merged cell) from white to yellow. I would also like the black
border line around the cell to change as well, but I am not sure if that is
possible?

Thanks.
