Created Unassigned: Issue: This control only accepts strings or null [15]

Hi,

Thank you for this useful tool.

I ran into an issue when I am using the tool. When I write the Latitude and Longitude the LocalAddress web resource is loading the location correctly. But when I Right Click on the map to load the values it gives this error " this control only accepts strings or null". event when I clicked on FillLatLong the same error appear.

I specified only 4 fields but then I used 2 fields of them Latitude and Longitude.

Please advise.
