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! ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/1/4180d1342cf6ab240fea447029f1c436865b1419.png) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/8/089eee428af02c9af67f9452072c4dea1e533be9.png) ---

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… 😢 ---

> [@anastasiamunteanu048](#): > > 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. ---
