Here's mine
My final code looks like this and it works.
Private Sub OKButton_Click()
Sheets("Sheet1").Activate
NextRow = Application.WorksheetFunction.CountA(Range("A:A")) + 1
'Application.WorksheetFunction.CountA (Range("A:A")) + 1
Cells(NextRow, 1) = TextName.Text
If OptionHS Then Cells(NextRow, 2) = "High School"
If OptionCollege Then Cells(NextRow, 2) = "College"
If OptionGrad Then Cells(NextRow, 2) = "Grad School"
TextName.Text = ""
TextName.SetFocus
End Sub
