Getting big numbers in LatLon.. help !

I am pretty sure this has something to do with projection coordinates rather than the GPS coordinates...
I would really appreciate it if someone could help me convert these coordinates back to normal GPS.
btw, for Israel, is that projection ok or should I have used  EPSG:2039 ? as in here : http://spatialreference.org/ref/epsg/2039/

Here's the site showing the problem. Just click around and you'll get the read I am getting...
Thanks !

Re: Getting big numbers in LatLon.. help !

Hi man, It happened to me 2 weeks ago. Try this. I made it in vb.net
Public Shared Function WGS1984toLonLat(ByVal x As Double, ByVal y As Double) As Double()
        Dim ret(1) As Double
        ret(0) = (x / 20037508.34) * 180
        ret(0) = 180 / Math.PI * (2 * Math.Atan(Math.Exp(ret(0) * Math.PI / 180)) - Math.PI / 2)
        ret(1) = (y / 20037508.34) * 180
        Return ret
    End Function
