Hi,
Well this really depends on where you are going and what you are trying to do here. Some specifics would help. Maybe this will get you started ...
Sub foo()
Range("A1").Value = UserForm2.ComboBox1.Value
Workbooks("Book1.xls").Worksheets("Sheet1").Range("A2").Value = UserForm2.TextBox1.Text
Workbooks("Book2.xls").Worksheets("Sheet3").Range("A3").Value = UserForm2.TextBox2.Text
End Sub
If you need other help, just post back.
Be sure and be as descriptive as possible when posting as this will get you the best possible help quicker.
