Hello! I came back with yet another question 
I’ve been working on an app that, once someone clicks a button titled ‘add spot’, it would retrieve the user’s current latitude and longitude using the location sensor and then would compare the value with its first 3 decimals with the latitude/longitude from airtable. The ‘alert’ value is supposed to change from 1, to 0 if your current latitude=latitude value from airtable, and, respectively, to -1 if current longitude=longitude value from airtable. If the condition (‘alert’=-1) is fulfilled, then it’s supposed to show an alert, and if it’s not, then a marker should be created and shown on the map.
After testing it, I noticed (using a label) that the 'alert’s value remains 1, the user’s coordinates are added to the airtable, yet no marker is added on the map. What’s the issue and how can I fix this?? Thank you so much!
Can you explain why are you using get property ..... j in your for each loops?
Well, I thought this could be a way to get the value of the latitude/longitude in each ‘Latitude’/‘Longitude’ row, by going through each row with ‘j’ and getting the value each time, but I may be wrong!
In your blocks, you are using list of values which will read the column and provide a list of all row contents for that specific column. So just use the j separately without the need of the get property.
It works!! Thank you so much! However, there’s still no marker added on the map… 
The Add Marker block expects numbers but the Get Current Location block provides and Lat/Lon as text. You need to convert them to numbers by adding 0 to them so that they are accepted by the Add Marker block.
Thank you very much for the help!!
