If T_ANAME.Text = "" Or R_MALE.Checked = False Or R_FEMALE.Checked = False Or R_OTHERS.Checked = False _
Or (C_COUNTRY.Text = "-- Select Country --") _ Then

I referred this page too If Statement With Multiple Lines
Remove the extra _ at the end of the logical statement.
If T_ANAME.Text = "" Or R_MALE.Checked = False Or R_FEMALE.Checked = False Or R_OTHERS.Checked = False _
Or (C_COUNTRY.Text = "-- Select Country --") Then
' do something
End If
