Closing Excel UserForm on CommandButton click

I have a sheet that has a ListBox. The sheet code has a ListBox_DblClick sub that launches UserForm1. UserForm1.CommandButton1 launches UserForm2. The user may input data in UserForm2 then press UserForm2.CommandButton1 which launches a sub in a module (yet to be written) and closes UserForm2.

With the code below, both UserForm2 and UserForm1 close. I just want UserForm2 to close upon click of UserForm2.CommandButton1.

Any thoughts on what I'm doing wrong are appreciated.

UserForm2 code

Private Sub CommandButton1_Click()

    Call UpdateBids(TextBox1.Object.Value, TextBox2.Object.Value, ComboBox1.Object.Value)
    Unload Me

End Sub
