get values from sqlserver

Hi everybody,

I would like to retrieve data from db whenever i click on a button. I have a table for questions and another table for options. I select questions randomly and trying to get the corresponding options but my code below only returns options one time and stays there even though the random number changes. As an example, if random number is 1 i have options a,b,c,d for question 1 and if random number is 2 i have options e,f,g,h for question 2, etc...
I can't see where i am wrong here. Please help me on that subject.

Thanks


Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = ""
Label2.Text = ""
Label3.Text = ""
Label4.Text = ""

RandomNumber = RandomClass.Next(1, 4)

Label5.Text = RandomNumber

sql = "SELECT option FROM options where question_id=@RandomNumber"
da = New SqlDataAdapter(sql, con)
da.SelectCommand.Parameters.Add(New SqlParameter("@RandomNumber", SqlDbType.Int, 10)).Value = Convert.ToInt32(RandomNumber)

da.Fill(ds, "Options1")

Label1.Text = ds.Tables("Options1").Rows(0).Item(0)
Label2.Text = ds.Tables("Options1").Rows(1).Item(0)
Label3.Text = ds.Tables("Options1").Rows(2).Item(0)
Label4.Text = ds.Tables("Options1").Rows(3).Item(0)
da.Dispose()
sql = ""

End Sub

I fixed it thank you :)
