VBA Userform Control("ComboBox" & i) issue and calling moduel

[finaljustice]

Hello,
Why won't "control()" work inside a moduel which is called uppon from a click action of a button??
Basically this code works fine: (inside a module and the userform button calls this macro)

Sub test1()
    If UserForm1.CommandButton1.Caption = "Unlock" Then
        UserForm1.ComboBox2.Enabled = True
        UserForm1.ComboBox3.Enabled = True
        UserForm1.ComboBox4.Enabled = True
        UserForm1.TextBox19.Enabled = True
        UserForm1.CommandButton1.Caption = "Lock"
        
    ElseIf UserForm1.CommandButton1.Caption = "Lock" Then
        UserForm1.ComboBox2.Enabled = False
        UserForm1.ComboBox3.Enabled = False
    UserForm1.ComboBox4.Enabled = False
        UserForm1.TextBox19.Enabled = False
        UserForm1.CommandButton1.Caption = "Unlock"
    
    
    End If

But if I tried it like so:

Sub test1()
If UserForm1.CommandButton1.Caption = "Unlock" Then        For i = 2 To 4
            Controls("ComboBox" & i).Enabled = True
        Next
        
        UserForm1.TextBox19.Enabled = True
        UserForm1.CommandButton1.Caption = "Lock"
        
    ElseIf UserForm1.CommandButton1.Caption = "Lock" Then
        For i = 2 To 4
            Controls("ComboBox" & i).Enabled = False
        Next
        
        UserForm1.TextBox19.Enabled = False
        UserForm1.CommandButton1.Caption = "Unlock"
    
    End If
End Sub

If I use this code above INSIDE the button code it works. Am I missing any coding?
A variable declared Public can be accessed either codes inside userform and moduels?
Thanks for your time!

You are missing UserForm1 in front of Conrtrols.

Ohhhh... damit. That did work perfectly!!
Thanks for the quick answer!! Just the last part, are Public variables read even in userforms?
Thanks once again.
