The lat and long values for the first “call” block should be the same as they are in the second. So remove the zeroes and replace them with the in list blocks that you have for the second.
Ok cool, thanks, I will try that.
Yes!
Cool thanks for your help, I will go test it out.
I have tested it, and there are a few things that don’t seem to fully work properly.
The Green marker did not ever appear.
The markers appeared at random time intervals even though I kept the timer at 60 seconds.
The app stopped adding markers after about 15 minutes.
The Map every few minutes did a random buzzing motion and kept changing the positions and zoom on google maps without me touching it and would not stop, this one I don’t expect you to be able to fix, but the others seem fixable.
Many Thanks Levi
I understand there is a lot to unpack I thought it’s just better to explain everything at once as it could be a simple mistake I have made or something like that. 
I really appreciate your help, I could not have gotten to where my app is now without your help.
Can you try this demo and see if it’s any different?

The demo is the first screen in the project. I had to zoom in really far to see the markers but I do see one green and a bunch of red.
Ok, I will try that today, Many Thanks Levi
You’re welcome. I had some issues with my own demo. In several cases, it colored one older pins green as well as the current/latest position pin. I don’t know if it would help to add a wait block within the “count 1 to …” block but it might. I’d try a small wait like 0.03 seconds first and then increase from there to see if it makes a difference.
Do I have to connect it to my own data source to get it to work, because after I click the button it doesn’t place a marker?
Also, should I be using Google Sheets or thinkable built-in data storage?
I used a local data source. So I think you can use the one I added to the demo or you could certainly create your own data source.
Ok, I will test that out.
When I make a local dada source though thinkable after I make it and select it and add it to my project, it does not come up when I am using the blocks to change where I send the data and collect the data, am I doing something wrong or is it a problem with thunkable.
Many Thanks, Levi.
This is a bug in Thunkable. When you create or change a data source, you have to drag a new block from the drawer onto the Blocks tab. The existing blocks will not have the correct slots for that new/changed data source.
Ok, thanks I will try that.
Even when I drag new blocks in for the “list of values in” block it still does not come up with my new local data source, what should I do?
Thanks Levi
It could be this bug that I reported:
You could try going to the My Data Sources tab at Thunkable and clicking the Sync with Source button for that new Data Source. And then adding a new data source block from the drawer. But if that doesn’t fix it, I would:
- Add a comment to the GitHub issue I linked to above. The more users who report the problem, the more likely it’s going to get addressed soon.
- Contact Thunkable Support for help.
I think it is the bug you reported, In the meantime what should I do? is there any other way?
Many Thanks, Levi
