I am reading rtb1.Lines

   Street addresses are in the rtb1.lines

For Each nLine in rtb1.Lines
   If nLine.Contains("_") Then
       sString = nLine.Substring(0, nLine.IndexOf(":- " & txtStreet.Text ' <--- heresd the problem
   End If

txtStreet.Text some times the addresses ... well I the variables that would contain the address dont always have the right address ... when that hap[pens variable returns NULL and it stops
at sString because of it ...

I hope I am explaining this ok ... here is what I am wanting to know ...

If a variable that is supposed to return a lat & lon has either  nothing or something otther than lat & lon how could I ignore anything but lat & lon
