How do I create a geopoint with passed parameters?

[JoeLivoti]

I have a survey that I have passed the latitude and longitude parameters from a point on the map. I need to create a geopoint from the lat and lon field. I would like to put in the default field. The lat and lon are already in decimal degrees. I've already read GeoPoints and Calculation on Geopoints and I'm still stuck.

Hi Joe, 

There are 2 ways to set the location of a point based on your description:

• Include the location in the URL parameters using the center=<lat>,<lon> parameter
• Calculate the geometry using something like concat(${lat},  ' ', ${lon})

@JamesTedrick as posted here I opted to simply use the "&center=<lat>,<long>" option. This works to place the point on the correct location on the map within a survey. However, the warning message shown below pops up after a few seconds unnerving the user. Is there a way to suppress this somehow? (my Geopoint must remain editable so the user can fine tune the location)
