Hello. I am trying to set up markers on a map based on a small dabatase that I have in Airtable. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/1/91c09b717279e376dbb4abd9d563032714fc4229.png) I filtered, using this function based on [Google Map Markers From Firebase - #10 by jared](http://community.thunkable.com/t/google-map-markers-from-firebase/73100/10) by @jared (I have actually been searching all day long in the forum and youtube for fixes and different codes approaches with no positive results) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/c/dc8ae5ca0858fc0d7f4d8298f3a17967ade60d20.png) Now, it doesn’t show an error, but always crashes. However, when I add an **If function** to skip the loop when it finds an _empty value_ it doesn’t crash. Actually I am guessing it doesn’t do anything, just skips everything. This tells me that there is some kind of error in the communication between Thunkable X and Airtable because the Table does not contain any null or empty cells. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/d/1dd559c464951a61a6ae12575ba5c1812b10e897.png) As the crash is happening before I call the function that adds the Map Marks that I want, I don’t believe it is an issue with the map itself. (i don’t have it currently active, the function I mean) I have tried running the app both on Android and iOS, having the same issue. Thank you for reading, I will be pending for a response. ---

is property latiitud stored as a string or integer in airtable? have you tried this? since you are checking if the text is empty in your logic, you should force the response from airtable to be a string. i looked back at the screenshot above and notice you have latitude stored as an integer. ![Screen Shot 2020-05-19 at 9.35.06 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/5/950d39f903d7e83bf47be73ae269c353124e63ce.png) ---

Thanks for the reply. The problem is not in that part of the code but somewhere here. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/e/0e00b050ce525c0dd5cd430b922766451c4be0d4.png) I really don’t care to check at the end if it’s empty or not, I just did it for troubleshooting purposes. In Airtable I have “LATITUD” and “LONGITUD” as Numbers ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/0/50626b81dac42c0d4f4493926b9c51f2343b32f5.png) Columns “NOMBRE” as Single Line Text and Column “OBSDIREC” as Long Text. Do I have to set all of them as text? Even if the response I need for the variable Latitude and Longitude in the SetMapMarker has to be an integer? ---
