That idea almost works except is it still difficult to work out which marker is the most recent from the user’s perspective, is there a way I can make the marker be green for example when it is the most recent, the change to red after a new marker has been placed? Many Thanks Levi ---

In your `count with i` loop, you’re cycling through all of the lat/lon values and adding markers. But the last row in the data source contains the most recent/current location. So in that loop, add an If block that says if i=length of app variable latlist then set pinColor to green (or whatever color)… else set pinColor to black (or whatever color). ---

Yes. ---

I have tried what you have said but it does not let me connect the blocks together? ![Screen Shot 2022-10-01 at 10.47.29 am](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/d/0d0db86621b00cd568efb7a22ec35eb82f732724.png) ---

I have tried to do what you have said here, but it does not seem to let me add the colour part. ![Screen Shot 2022-10-01 at 12.11.05 pm](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/9/49086263569d8cc39cd2f7a6827d51cab812c6e5.png) ---

Or should I try something like this: ![Screen Shot 2022-10-01 at 1.56.02 pm](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/2/8/280918f315ed715ef3e413d9336444e3c3c9e513.png) I have no idea if that will work. ---

You’re on the right track but if you read my post carefully, the If condition I suggested is `i = length of app variable latlist`. In that last screenshot, you have the If condition as `length of i = app variable latlist`. That won’t work. The point of checking the value of i is that it’s the loop index. So when i is equal to the length of the list that you are looping through, that means you’ve reached the last item in the list. ---

So should I swap them around like this: ![Screen Shot 2022-10-02 at 6.45.58 pm](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/1/7146051509ca2071ba98fcec01bf4fb1d8c6e7a1.png) ---

Nope, that’s still the same thing. You just switched the sides of the same equation. Here’s what you need: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/4/f47ea67c016f07ce4cf449d19aed01518860490b.png) ---

Do I keep both of the blocks to place markers? ---

Yes. Because the `if` condition has two possible values: true or false. So if true, then you’ll create a marker with a green pin; and if false, then you’ll create a marker with a red pin. ---

Cool, thanks also do I need to change anything on the first marker to do with the lat and long, or should I keep them as they are on 0? ![Screen Shot 2022-10-04 at 4.32.58 pm](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/8/c8db3240fc2309df892b3272931d21d584112a7c.png) [Previous page](https://community.thunkable.com/t/how-to-remove-marker-on-google-maps-once-another-marker-is-placed/1999758.md?page=1) [Next page](https://community.thunkable.com/t/how-to-remove-marker-on-google-maps-once-another-marker-is-placed/1999758.md?page=3)
