I didn’t know how to title this, more power to you if you think of a better title. The top yellow rectangle does work, while the bottom red rectangle does not work One of my screens in my DB is called Start so I know my work is double checked for me ![Screen Shot 2022-07-10 at 7.31.15 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/9/9989647e4ab1f378c1d4f45c37f5b6e2439f47ec.png) ---

There’s a ton of missing details here that we would need to be able to help you troubleshoot this. If you want to provide the value of each `get property of object` block then we could probably figure out why this doesn’t work. ---

From the way you are coding the elements inside the loop and comparing them with the direct assignment, I can see a difference there. What would be the content of **j** in the first round? would it be **ROW-Start** , or just **Start**? In the `set Row` part you are using **j** as if it contains **Start** and if this is true then the `get property of object j` should fail because it expects **ROW-Start** as it is mentioned in the blocks above the loop. The other thing is: the loop block `for each item....` will only recognize fully formed lists in JSON. Most of the time you do not have a list but only a JSON collection which will not be identified as a list in the loop block. In such cases you will need the block `get object properties....`. ---
