I have the following code for a Check Box (ActiveX Control) using Excel 2013:

```
Private Sub CheckBox1_Click()
If CheckBox1.Value = True Then
    CheckBox2.Value = False
Else
    CheckBox2.Value = True
End If
End Sub

Private Sub CheckBox2_Click()
If CheckBox2.Value = True Then
    CheckBox1.Value = False
Else
    CheckBox1.Value = True
End If
End Sub

```

What it does is simply uncheck Box 2 if I check Box 1, and vice versa. But if I use the above code for a Check Box (Form Control), I get a "Run-time error '424': Object required" error message. Does anyone know of a solution?

UPDATE: The same code above that I tried using in a file that I got from [Bytes](https://bytes.com/topic/visual-basic/answers/888416-why-vba-excel-not-finding-checkbox-object) somehow worked. Since I'm a newbie in VBA, I think I'm gonna have to sit down and study how Excel, Macros & VBA work together. Once I find out the source of the problem (that technically I created myself), I'll post an answer here as to how I figured it out. Thanks to everyone that posted comments & replies. I really appreciate it!
