Hello,
I have gone through the tutorials for geocoding and for getting data
from the mysql database into the google map. I get displayed output
for the xml file, but when i try to load the map using the code given
in the tutorial I can't get it to work. I feel stupid bc the entire
code is just sitting there, but for some reason I can't get it to
work. It's worth noting that I did not just simply use the coordinates
they gave me, but tried to use it in my own database. Here is the xml
output I get from (genxml.php), followed by my .html file. Any help is
appreciated! Thanks!
<markers>
<marker name="Northwestern University" address="Chicago, IL"
lat="41.879536" lng="-87.624336" type="Interview"/>
<marker name="Emory University" address="Atlanta, GA" lat="33.754486"
lng="-84.389664" type="Interview"/>
</markers>
Here is the .html file I have:
