Hi Eirik,

Because you are using RadioButtonLists, you have to loop through each item
in the list to see if it is selected. Then, if it is you capture the text
for that item. Once you have the text, you need to go one step further, to
convert the text to an integer.

Try this?

Dim Int1a As Integer
Dim Int1b As Integer
Dim intCounter As Integer
For intCounter = 0 To RadioButtonList1a.Items.Count - 1
If RadioButtonList1a.Items(intCounter).Selected = True Then
Int1a =
Convert.ToInt32(RadioButtonList1a.Items(intCounter).Text)
End If
Next
For intCounter = 0 To RadioButtonListlb.Items.Count - 1
If RadioButtonListlb.Items(intCounter).Selected = True Then
Int1b =
Convert.ToInt32(RadioButtonListlb.Items(intCounter).Text)
End If
Next
lblLabel1.Text = (Int1a + Int1b).ToString

Does this help?
