Some comments on the version of your file that I see now: It is starting to get very confusing. I would suggest creating a single function to process your xml data (unless you really want to do different things with the different xml files), it would be easier to think about if the differences were encapsulated in the xml file (but it is software, so it can be done either way...) It looks to me like your datatype2() function is set up to process the returned data from GDownloadUrl, but it unlike the datatype1() function it never calls GDownloadUrl. You now have 2 different createMarker functions, that is going to cause confusion and possibly work differently in different browsers. -- Larry > > On Apr 14, 2:30 pm, "[email protected]" <[email protected]> > wrote: > > > > > On Apr 14, 12:05 pm, Mike <[email protected]> wrote: > > > > Thanks for you reply. > > > I did try that but it didnt work. > > > I uploaded what I have done so far, for some reason it just wont > > > remove the overlay.
