userform - help needed

Hello to everyone.
I created a userform (UserForm1), and inside this form I placed 20 textboxes and 20 checkboxes.
Everytime I make the userform to appear, I need all the checkboxes to be false and all the listboxes to be empty
One question at a time...
I can write down 20 rows to set each checkbox value=false but I would like to have something better
I tried

Code:

---

For i = 1 To 20
UserForm1.Controls("CheckBox" & Chr(64 + i)).Value = False
Next i

---

but it says runtime error, impossible to find the specified object
These instructions are placed in the command button macro, just before the UserForm1.show line

How can I fix the error?
Thanks to everyone

Hi Elane, welcome to the forum.

Try as below:

Code:

---

    Dim i As Integer   

    For i = 1 To 3
        UserForm1.Controls("CheckBox" & i).Value = False
    Next i
    UserForm1.Show

---

Unless your checkbox's are named 'CheckBoxA', 'CheckBoxB' etc.?

you may also try this on the Activate event of your UserForm

Code:

---

Private Sub UserForm_Activate()
    Dim ctl As Control
    For Each ctl In Me.Controls
        If TypeOf ctl Is TextBox Then
            ctl = ""
        ElseIf TypeOf ctl Is CheckBox Then
            ctl = 0
        End If
    Next
End Sub
