Hey guys,

Private Sub CheckBox13_Click()
Application.ScreenUpdating = False
Dim cell As Range
Dim InputValue As String
On Error Resume Next
Range("I8,I11,I14,I20,I23,I27,I33").Select
    If CheckBox13.Value = True Then
    With Selection.Interior
        .Pattern = xlSolid
        .PatternColorIndex = xlAutomatic
        .ThemeColor = xlThemeColorAccent3
        .TintAndShade = 0.599993896298105
        .PatternTintAndShade = 0
        For Each cell In Selection
        If IsEmpty(cell) Then
            cell.Value = "Enter"
        End If
    Next
    End With
    Else
    With Selection.Interior
        .Pattern = xlSolid
        .PatternColorIndex = xlAutomatic
        .ThemeColor = xlThemeColorLight2
        .TintAndShade = 0.799981688894314
        .PatternTintAndShade = 0
        For Each cell In Selection
        If cell.Value = "Enter" Then
            cell.Value = ""
        End If
    Next
    End With
        If CheckBox14.Value = True Then
            Range("I27,I33").Select
            With Selection.Interior
                .Pattern = xlSolid
                .PatternColorIndex = xlAutomatic
                .ThemeColor = xlThemeColorAccent3
                .TintAndShade = 0.599993896298105
                .PatternTintAndShade = 0
           For Each cell In Selection
        If IsEmpty(cell) Then
            cell.Value = "Enter"
        End If
    Next
            End With
        End If
    End If
Range("I8").Select
End Sub

Above is the code that I am using for a project. The basics of it is I am getting a couple of boxes to become highlighted and the word "Enter" appear when a checkbox is checked. Also, if there is data already in the cell then it is only highlighted in order to keep the data. It works as it is but because there are a lot of checkboxes, it is very tasking on the PC to even open the file. Any suggestions as to reducing the amount of code and making it more efficient is much appreciated.

Thanks,
