This is my last post about this app, I swear 🙂 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/0/e08fe6938ae5d49b09307eebe248a735350d83b1.png) When I open the map, the app crashes. I did the following: -checked the variable"alarma" and its properties(they’re all fine, so the problem is not there) -checked other things(everyting is functional until I “call Map1’s addIconMarker” -set the value of the latitude and longitude to numbers(converted from strings by using mathematical blocks) Something still seems to be wrong. Why is that? ---

Use direct number that you have in the latitude and longitude ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/d/bdebb39e5f335e7295bcd6e676d2000ba60c14ea.png) ---

Thank you, but I have to use the numbers I have stored in the firebase. ---

Can you explain a little more about why are you using a local variable to get a value from a cloud variable? ---

Sure! Those values that are to be stored are taken from another user. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/4/0414d1a6ad54ba32d5086126b121b9a5aeee2866.png) (this is from another screen) When one user clicks a button, that variable will create an object with the coordinate fields. Those are going to be used to add a map marker, in another user’s map. Basically, this should be a location tracker. ---

First of all, thank you for the videos but they do not show any map in the project and second anything to do with maps need to be run from the mobile not from the computer. Can you please record another video showing the map in the screen and clicking the option to add the marker? ---

This is what causes the crash ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/2/020ae56e42d5672d8ce3b690a16c4ba5726ee143.png) Try to remove them and test and it should work OK without crashing. ---

Make sure the `cloud variable` for the `description` is not **NULL** or currently just replace it with with direct text. ---

It’s not null. Replaced it anyways, and it still crashes.

“main screen voluntar” the one with the map component. ---

Not that easy @tatiang To go through his project you need to connect it to Firebase and then create a key with the User ID that you will login with and in that key create another key called `branch` with content `voluntar` to be able to reach the page when you login. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/c/8c502cdbb97dda65ab46ca3faa2a6bd68ee87223.png) After doing so, the next issue is the project does not allow anything with the `Map` component. I also created a simple project just a map and a button to click to add a `Marker` but it failed. I wonder if this has to do with the recent changes that @jared, @jared mentioned ---
