My script works, but when i added the ProjecttoLatLong it doesnt work.

I want it so that when i click on any point, and info window shows the coordiantes.

Thanks for any help. Much Appreciated

I made quite a few changes (lots of syntax errors), the biggest one being defining gsvc to be a geometry service. Try this code:

Hello THanks for the edits.

The PROJECTTOLATLONG function is suppose to make a info window pop up with the coordinates. Sort of like http://help.arcgis.com/en/webapi/javascript/arcgis/demos/util/util_project.html

Thanks.
