[Resolved] combo box help

[salating]

i have four combo boxes in my form, each combo box has 2 or 3 selections

i need to check each combo box for a selection, if nothing is selected i need to have a error message come up in a message box

each selection in the combobox is woth different points so i am using a counter and when the user click the button it shows the total points in a message box

If cmbAge.SelectedIndex = -1 Then
     MessageBox.Show("Please Select Your Age", "Error")
     cmbAge.Focus()
     If cmbAge.SelectedIndex = 0 Then
          intPtsCnt = intPtsCnt + 1
     ElseIf cmbAge.SelectedIndex = 1 Then
          intPtsCnt = intPtsCnt + 2
     ElseIf cmbAge.SelectedIndex = 2 Then
          intPtsCnt = intPtsCnt + 3
     End If
End If

i have one of these for each combo box

when i run the program and click the button all 4 error message boxes show up then it shows the total points, i want it to go through each combo box one at a time
