How can I refrence the text inside of a textbox through VB coding...

Situation: I have 60 diffrent check boxes. When one of them is
pressed it does the following...

If CheckBox1.Value = True Then
CheckBox1.Enabled = False
TextBox1.Value = "CheckBox1"
End If

I have a commandbutton I would like to enable the checkbox# from
TextBox1 value... I've tried the following but it's probally not even
close.

Private Sub CommandButton1_Click()
Dim LOCK1 as String
LOCK1 = TextBox1.Value
Lock1.enabled = True
Exit Sub
End Sub

How can I get this to work?
