Hi - I’m tearing my hair out with a problem and was wondering if anyone here might be able to help. I have an Airtable spreadsheet that looks like this: Name|Latitude|Longitude Bao|51.513256|-0.136554 El Pastor|51.505315|-0.091193 Xu|51.511144|-0.132614 I’m trying to create and display a list which shows the distance from an inputted location to each of these restaurants, and the name of each restaurant. I’m doing this using the Google Maps API. The output I get from this in the app is a list of the correct distances to each restaurant, but it just repeats the name of the last restaurant 3 times. e.g.: Xu 3248seconds Xu 177seconds Xu 2913seconds The distances are correct, and displayed in the correct order. I just can’t figure out how to display the correct restaurant name for each distance! These are my blocks - if anyone can figure out what’s wrong here, that would be absolutely amazing. Thanks! ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/e/5e3da8d2dc200569215d84f4a2be15837f4db4a0.png) To talk you through the blocks: - first call the Airtable spreadsheet - then begin loop for each item in the list - the green Web\_API block is using the Google Maps, using the coordinates of each restaurant from the spreadsheet - the purple API block gets the response; and then saves as a list the time in seconds to each restaurant (the big pink thing) and the name of the restaurant (this latter bit is what’s broken). ---

The problem is that the Web\_API.Get uses slow asynchronous call. A cycle has worked, as Web\_API.Get have not had time for it and, therefore, displayed the latest reading. You will need to modify the algorithm so that the next call to Web\_API.Get happened only after the completion of the previous call. Here it is necessary to use recursion, as Mark showed. > [@Asynchronous Blocks within Loops](http://community.thunkable.com/t/asynchronous-blocks-within-loops/33524): > > We recently had a bug reported by a user who was seeing strange behaviors within the “then do” part of a RealtimeDB.Save block which was within a loop block. The strange part was that even though each execution of the RealtimeDB.Save block was called with the current value of the loop variable (or something based on the current value) the blocks within the “then do” part always just saw the last value of the loop variable! This is a well known issue when using asynchronous function blocks (lik… I will think over such a block ---

On which screen and in which block is the code that does not work correctly? There are a lot of duplicate blocks in your code, an incomprehensible delay of 10 seconds, a lot of unnecessary variables, no checks for errors when getting data from the API. Try to simplify the code. The more blocks - the more mistakes. ---
