First of all, congratulations Kevin, this module is marvellous! I have installed version 01.00.09 under DNN 4.9.3 and it works a treat.
The only thing I am having trouble with is showing different information in the Point Description format and the Item Template. I want the Point Description format to show [ADDRESS] but not [DESCRIPTION], and the Item Template to show both. The reason is that the [DESCRIPTION] in my case is lengthy and not suited to the pop up balloon on the map.
When I try this I find that the Item displays the [ADDRESS] literally as "[ADDRESS]" and displays [DESCRIPTION] as the entirety of the Point Description format.
For example
Data
Address = "Norwich"
Description = "A Fine City"
Latitude = 52.616583
Longitude = 1.007463
Point Description format
[ADDRESS]
Lat/Long: [LATITUDE],[LONGITUDE]
Pop-up balloon
Norwich
Lat/Long: 52.616583,1.23362
Item Template
[ADDRESS]
[DESCRIPTION]
Item display
[ADDRESS]
Norwich
Lat/Long: 52.616583,1.23362
