Forms :: Adding Record To A Table From A Form

I have limited experience in Access, but I have managed to create a user form, where items are selected from comboboxes (Test results; when, who, outcome, etc)

At the end I have built in a command button that should add a record to an existing table, but so far no luck. I have used the following VB code for this:

Private Sub Save_test_results_KeyPress(KeyAscii As Integer)
Dim dbsICT_Test_Management As DAO.Database
Dim rstActual_test_results As DAO.Recordset
Set dbsICT_Test_Management = CurrentDb
Set rstActual_test_results = dbsICT_Test_Management.OpenRecordset("Actual_test_ results")

rstActual_test_results.AddNew
rstActual_test_results.Update
End Sub
